I have to learn about XHTML and CSS because the lovely template I was using for all my previous entries unaccountably added an extra column, thereby banishing the profile side bar to the bottom of the page. I don't know if it was as a result of my ill-advised fiddling or it didn't like the links and buttons I was putting in. It's all a learning experience I suppose - albeit a frustrating one.
09/05/06 Postscript - I fixed it! A problem with too many big photos kicking the frames out. It took a bit of trial and error to find though but I now know how to tweak a template.
