We recently did a large migration of nearly 100GB of forum content. In the process, we fixed a lot of broken links on the site, and overall things should work better.
However, an unknown number of users had their Profile Picture replaced with a generic “letter in a circle" image. I don’t know what caused this, or exactly who was affected, or I could probably fix it myself. If you were affected, please kindly go to your Account Preferences and upload a new copy of your Profile Picture to help people recognize your posts. (Some of you have already received DMs from me with this information, but the more I looked the more I realized that I wouldn’t reach everyone that way.)
I’m very sorry for the inconvenience!
