Also, which profile pic shows up in the forum? I tried one for both and neither showed up.
It's the little one, the 50x50 pixels. The 150x150 only shows up in your metaverse profile.
Also if you change them there is perhaps up to a day of latency before the new one starts appearing although it may be as quick as a few hours.
At one point I tried to add a moustache in paint but it took quite awhile before it stabilized. In the end it looked like crap so I went back to my old standby.
Depending on the age of the thread I didn't always have one.
I did not know that, but I made mine very soon after joining and (mostly) kept it ever since.
