It seems chat scripts like Flashchat are very CPU consuming and they interfere a lot with the other shared server scripts causing annoying lags. So shared doesn´t like Flashchat with 20 or more concurrent conections and will terminate your account if it goes very active. I can´t find a shared which officially allows active chats.

External IRC servers would be the logical but it is important to take the password from the forum to avoid false identities. Is there any solution to integrate a chat in a forum (like SMF) in shared servers?

Thanks a lot
