Nigel, you use the word "chat" often when you actually mean "discussion." The word "chat," on the internet, to my knowledge, means live, interactive postings. A chatroom is where you post and others post back in real time. A forum is not real time.

Point being, your link uses the word "chat" and if I did not know what "The Bar" really is, I would never click that link because I do not do chat rooms.

You could solve it by saying "Visit the bar, a shoot-the-breeze forum" or "Visit the bar for general discussion" or "Visit the bar for posts about anything and everything" or "Visit the bar, an Open Mic (general discussion) forum" or any number of phrases.
