Is it possible to find Blogs on, for example, travel without having a particular URL.

Yes. Use wordpress.com search, Topics search and Google search. See above.

want to set up my own Blog on Cruising but do not know how potential readers can find me.

They find you the same ways that you find them. That's why commenting on posts in similar blogs and meeting bloggers with similar interests in social networks is important.

For Google searches use this format and replace "keyword" with whatever word you wish:
keyword site:wordpress.com/

Example search string
Queen Victoria site:wordpress.com
results > http://tinyurl.com/csaobsx

For Topics (Tags page) searches see http://en.support.wordpress.com/topics/

1. You can set up email subscriptions by using this guide > http://en.support.wordpress.com/widgets/follow-blog-widget/

2. If you would like a follow button to appear on the bottom right hand corner of your site for those who do not have WordPress.com accounts see here >

3. You can also set up a secure contact form.

Social networking is strictly give to get. It takes months of posting frequently to attract viewers who will actually submit comments. The best way to get comments on your own posts is to leave meaningful comments on blogs with similar content to what's in your own blog. Set a goal of commenting on "X" number of blogs weekly and carry through.

though there are Google warnings about malware all over it.

Thanks.

I've taken off what I thought was the bad code, backed up my content and updated the WP operating system. However, there are 3921documents in the server, and according to google there are now 47 infected files.

A friend has tried scanning the documents using Dreamweaver to see if any of the text shows when you click one of their links, is in any of those 3921 documents..

Dreamweaver can't find any of it. I don't know what to do. I need a wordpress person.

Do you have any suggestions that might help?

Your followers receive an update, either on their Read Blogs page or via email (or both, depending on their settings). There are several different ways that readers can start following your blog. http://en.support.wordpress.com/followers/

Go to your site stats page and click “Totals, Followers & Shares”
Click the Blog link under the number and the Site Stats » My Followers page will open. Click the Email Followers link.

Is this possible?

Cheers
Matt

Take care and be safe.

That is one of the great things about blogging here; it is probably the most secure blogging platform there is.

I hope it did not scare too many people.

First off, happy holidays. :) I hope this time of the year, chilly for many of you, has given you time to enjoy family, friends, and loved ones and reflect on the year before and the year to come.

My last message to you this year is an important but unfortunate one: we've fixed a pretty critical vulnerability in WordPress' core HTML sanitation library, and because this library is used lots of places it's important that everyone update as soon as possible.

I realize an update during the holidays is no fun, but this one is worth putting down the eggnog for. In the spirit of the holidays, consider helping your friends as well.

You can update in your dashboard, on the "updates" tab, or download the latest WordPress here:

The official release announcement is here:

Merry WordPressing in 2011,

Additionally, in the two years I've used .com, I have never had this explained to me. I sincerely appreciate your information, but perhaps .com users should not be sent version update information if it applies to .org users only. I do see that the download link is a .org link now, but it did not register with me, so I did download it whether it took or not.

Again, thank each of you for your patience.

Here is the bottom line: You are always at least on the latest official version of wordpress, and at times you are ahead of the game here and on a version that has not yet been released to the public. But again, it is a modified version no matter what so it cannot be accurately tied to a specific version.

As to when wordpress.COM does updates, they do them all the time here, continuously. This is a constantly changing and evolving platform.

WordPress.COM does the updating for you - you have no control over the version of the software running here. You can't update ANYTHING on your blog except the Pages and Posts that you write and the sidebar contents etcc.

Is there a way for me to tell or do I perpetually wonder?

Thank you

The version number does not matter because of the above - but you are running at least the latest version - many times WordPress.COM is running ahead of the latest version.

Thank you
Santhi
