I am at work on the template I use for this blog again, making several changes to improve / clean up the code. Sometimes this will mean I have to republish one or more of the old entries. This isn't a problem if you are visiting my site since everything will still show up with the same date, and in the right places. However, those people reading this through the Atom XML Feed may see these entries show up again.
Over the past few days I believe I took care of all the entries which needed to be fixed to work properly with the template and setting changes, but this caused a few entries to reappear in the feed.
Sorry. I should not have to change anything else, so we shouldn't have to worry about this in the foreseeable future. (Although I am still working on template, so we can't be sure...)
Anyway, just wanted to let you know what happened and let you know that it shouldn't happen again.
