You never get a better chance to make a good first impression. Unfortunately, the registration form in Community Builder ain't all that attractive. Fortunately, there is a solution to this problem!  mod_Skin_CB_Registration from JoomlaWebDesigners.com lets you quickly skin the community builder registration form. It comes with an attractive blue template similar to the registration form at JoomlaWebDesigners.com .

Never show your new users an ugly registration form again.
