You've posted so many times about this and nearly all your queries have been closed (by staff). Please - if you must ask support questions, only ask them once. And be patient for replies. I'm replying to this one - though it's an earlier on - so that you don't do this again.
Firstly, your first query - four months ago - was answered by Staff here. Perhaps you didn't see the reply. Here it is:
If you want to see the topics you've posted, you can see them all here, via your forum profile:
Okay, now some advice from me:
The tags (topics) page does not show all posts from everyone all the time. There are millions of people using blogs on WordPress, if they were all to show, the topics page would be overloaded.
However, a few tips (having looked at your blog): don't repeat the same tags as categories - both tags and categories are counted just as tags by WordPress.com so when you use two fo the same (for instance, a 'health' tag and a 'health' category, that's unecessary.
Use as few tags and categories as you can get away with and try to think like someone who is looking for them, in other words, use more commonly searched for terms, and use popular ones. I never use more than 10 tags and categories in total.
The other thing is - from what I can see from your home page, most of your posts are reblogs. It's much more likely that the original post will appear on the topics page than reblogs, as they were there first! Do yourself a favour and fill your blog with your own, original writing, not other people's - it's not a good way to get a readership for your own blog - people want to read original posts.
