For the url fields (facebook, twitter, etc), I got all kinds of input, most of them are not valid urls. But the pretty icons will always show up regardless.  How can I enforce it to be the right format?  I put some regular expression  stuff under "Manage Profile Properties" but didn't work.  

I hope this comes out right in the forums, if not, check the links for some others:

(http|ftp|https):\/\/[\w\-_]+(\.[\w\-_]+)+([\w\-\.,@?^=%&:\/~\+#]*[\w\-\@?^=%&\/~\+#])?

Sources to have a look at for other good examples such as zip codes, phone numbers, email:

Edit: I've not tested against the "asURL" Data type yet.

goBlanks,

That worked. I don't know why there is no "asURL" data type available but I changed that into "Text" and it worked ok.

Thank you for the help!
