[Bug] Tags

when ever you post a thread you can chose to specify index tags to help the search engine.
but .. you can't add more then one tag.

it says your cuppose to seperate the tags with commas, but if you do that you get this:
"'Tag, bug, forum' has not only alphabetic and digit characters"
if you remove the commas .. then it's ok .. but as far as i understand it .. the script wont index the tags as seperate tags then ... but rather as a single string.
