Sorry for the delay, I've been on holiday.
digiSal - the writer of the Whoson mod said he would look into adding this to his mod, so you'd have to get in touch with him to find out.
tenl - the only change in 1.2.2 was one line for compatibility with the MSN Messenger mod, although it's by no means foolproof.
FAQ - if you're referring to the 1*1 pixel avatars problem then as is mentioned in the mod itself that's a known problem with the javascript code, which I borrowed from BHRA Webmaster, and he doesn't know what's up with it. You can disable javascript resizing by setting the width and height values to 0. Besides that, unless you know another way to intelligently resize images, we're kind of stuck. If it's not that problem, let me know what is the problem.
As for all the problems with getting the tables right, that's all caused because I've found it's virtually impossible to tell 100% whether the Calendar, Chat and MSN mods are also being shown in the Info Centre. Therefore it's impossible to correctly set the rowspan of the Recent Users cell "out of the box" for everyone.
The fix is to change the following line manually (preferably in the mod file before you apply it so that you can uninstall it later, or after you apply it it's in BoardIndex.pl)
$rul_rowspan = ($username eq 'Guest') ? 6 : 4;
to increase both numbers by 2 for every mod you have that hasn't been auto-detected. So if you have the Calendar mod, and it hasn't been detected by the dodgy built-in compatibility, change that line to
$rul_rowspan = ($username eq 'Guest') ? 8 : 6;
I hope that explains it.
