Posting Code in Simpleboard

I've finally solved the problem with the Forum (Simpleboard) stripping out all code tags and its contents: it's an issue with Mambo 4.5.1! Mambo filters the variable "message" used by Simpleboard for the message text and strips off all tags (strip_tags). I've reported the "bug", which can be prevented by changing Mambo's index.php, at mamboforge.net.
