"You have encountered a forbidden .html error, and have may used one or more of the forbidden words while trying to include a link in your message. There are certain words, including 'class' and 'style', that we do not allow while creating links in your messages because they are a doorway into several js exploits. Unfortunately, if you should have words that have 'class' in them (e.g., classify, classic, etc), they will also be forbidden. We are looking to find the best solution for this problem, and we apologize for any inconvenience this may cause."
Also, why do I get a formatting error when I cut and paste something into my post and the formatting is wrong and there is an extra space that is added to my message?
Another thing. When I private message someone, it sometime gets and html error and the message cannot be sent?
