It's my understanding from this previous post that the url for for wordpress.com blog is http://bellphotos.wordpress.com/ It's necessary for you to post it when you post to the forum or alternatively, you can link your username to it.
It’s very easy to do. Here’s how to link your username to your blog in your blog Dashboard –> Users –> Your Profile. Then scroll down to where it says ‘Primary Blog‘ and fill in the address of your blog and then click ‘Update Profile‘.
Once you’re done click “Update Profile”. Voila! Now every time you sign into the forum we can all click on your username and your blog will be linked to it. And every time you leave a comment on a blog your username can be likewise clicked and your blog can be instantly located.
In an earlier post you made to the forum you stated that you lack experience in CSS editing. http://en.forums.wordpress.com/topic/wider-blog-and-full-size-pics?replies=12 There is no staff support for learning CSS, therefore, your choice appears to be to switch to a wider theme.
