I have toyed with creating a web 2.0 tab - what I would like to see is two fold:

1 - A tab that has the ability to link to a users myspace, linked in, technorati, etc. I can accomplish creating the links as if they are webpages, but simplicity here is key - I also tried adding an image to the beginning of the field text, but it outputs the raw HTML. I think this feature would be a great step for community builder.

2 - A % complete statement, I know that on my linked in, and several other sites, it says - your profile is X% complete, and it drives me nuts to not be 100% - I want to put my visitors under the same stress - LOL.
