You do know that that's not valid javascript and will cause an error? Don't just copy/paste some code from a script and expect it to work. Replace linkify_plain:function(text) with function linkify_plain(text)

Sorry I was using it in the context of...

object = { linkify_plain:function(text) { //code here } }

This function works OK, but actually it will replace all links including links in tags (IMG, existing A HREFs, STYLE etc.)
