It seems that the link to the User CP for forum members to update their control panel is missing from the forum header and footer.
See this discussion for details.
We all know, but thanks for bringing it up once again 
This will be solved (hint hint) when (or maybe this should be an IF) the forum will finally be moved to an all new and better software. I've placed this on my wish list for Xmas.
OK, didn't see it in the Bugs section and just wanted to make sure.
Thanks.
