[quote] - Max avatar dimensions changed from 150x150 to 150x200 (150px wide, 200px tall)
 - You can choose an image larger than 150x150 and the guild will resize it to 150x200 for you (maintaining aspect ratio)
 - You must upload your old avatar manually to move it into the new system. In a week or so, I'll be removing all old avatars. If you go to your "Edit Avatar" form, you'll be able to access your old avatar so that you can conveniently upload it into the new system. [/quote]
Well, at least we now know where the avatars went. On the sidenote, reply box now seems to lack formatting options, and the hint boxes don't seem to work... Oeh. Edit: And now they're back. 

Edit#2@Jack: It seems that you will need to replace the links to the earlier character sheets with ones from the chain-link symbols in the corners of the sheet-posts... (Next to "Wiew Raw" right-click and copy link address - if you just click it and then copy the address bar, you'll still have the broken links.)
