1. The hack caused serious security issues, and was thus removed. I don't know if it's ever been fixed or not. Try searching our 6.1 Mods Beta forum.
2. No published hack that I know of. Just go into the
public_topic_page.pl template file and edit the html to your little heart's content.
But if you try searching the 6.1 Mods forums, you may find one, who knows.
3. (Yet again) Search the 6.1 Mods forums (not sure wehther it's beta or final) for "topic starter" and you should find it.
