Hi all Cpner's
It looks like we are finally going to get the site upgrade we need to improve security and other features. Last time this happened we found that not all the modules transfered over. The one that was the biggest problem for people was the Bookmarks module-- this is the feature that allows you to keep a list of links within the site on your home page. I don't know any great way to do this except manually: click 'manage bookmarks' and go to each page, saving the url to your browser or to a text page.
It's possible that other things like messages could be affected. So you might also save important messages that you've kept in your inbox just in case. Keep your fingers crossed! We should have some improvement to spam and other accumulating problems soon.
