Hello!
I think that a good idea is something to edit the custom profile fields... in the profile view in the viewtopic a button, and then when you press you can edit all the fields... something like this:

Normal view:




To edit:





I think that is fast and easy :)

Though that would be somewhat nice I think that's really bloating since they can edit it in their profile or in their user controls.

Yeah, I agree with TheMorrigan, it would make it more bloated than it has to be.
