Slight difference - the avatars are small & off to one side, whereas that sig was a) in the middle & b) enormous, there was no way you could miss it filling practically the whole of the screen. Yes, I saw Supernova's avatar but notice I didn't complain about that as it didn't near enough jump off the screen & hit me. Haven't noticed Bowen's latest - must have a look now!
There was a clean-up of avatars sometime earlier this year, as they were getting very smutty. Keep pushing it & it may well happen again
