Hello All,
We'd have a few reports of issues changing changing avatar's on the forum. I found the issue and corrected it just a moment ago ( as evident by my new avatar ).

Sorry for the inconvenience this has caused.

Quick links:
Change your Avatar -- The picture everyone sees next to your name in posts.
Change your Profile Picture -- The picture people see in your profile.
Edit your Signature -- What shows at the bottom of each of your posts.

These settings are normally accessed via the 'Settings' option at the top right of any page within the Forum.

Thanks,
LK
