I just started testing this software, and I like it, but for one thing: I can't figure out if and how to have any additional widgets in the widget columns. Is there such a thing as a login widget, for instance? I'm new to this whole thing, so please forgive me if this is a silly questions. I dabbled in Joomla very briefly, decided it's a bit too much for me and for the folks that will help me administer the site, and decided to go with Wordpress, but I am a bit confused at this point... Any help would be appreciated.
The other software i'm testing is the Artisteer, but that does have to have additional widgets - of course it's also far, far from free, especially the full version.
