Oh good, a language thread...
these kinds of threads are fairly frequent, and I understand that they become tiresome, however, I like them. I've always been a fan of language.
Language is an artform, even in countries where there are official standards, languages that are in active use evolve, and the bigger thing, is the meaning of a phrase, is more in the head of the listener, than the person speaking....
Anyway, MarkTime says 'forum' is correct. It's the word most understood, and if your goal is to be understood, use that word.
Beyond using words people have half of chance of understanding, you also have to carefully pick your point.
And finally, look a bird.
Sorry, that was all for me. :-)
