I’m doing that because I don’t know what I’m doing in this format, it is utterly unfamiliar to me. I’ll fix that. Do you think that’s why the entries are posting twice, that they all have the same name?
I don’t know, but unique titles for each post on a blog are less confusing to a human reader.
Because you are such a new blogger let me suggest that you work through this very useful tutorial to get you familiar with the wp.com platform—it is well worth the time to go through it: http://learn.wordpress.com/
You can also get some ideas about how to search the support forums for questions you have as you become comfortable with this platform: http://en.support.wordpress.com/
If none of that helps, then ask your question again in this thread. We are mostly volunteers here and are happy to answer questions…
