We have just added a bunch of new profile fields for social networking.

They include the following:
Skype, Facebook, MySpace, Twitter, Google+, LinkedIn, Youtube, DeviantArt, Pinterest

You also have the option to have these enabled on registration to be filled in.

Enjoy,
CreateAForum.com

Get adding if you'd like 

I've only enabled Facebook and Twitter, but if you really want one of the others let me know!
