If one means "the community belonging to the artists" then "Artists' Community" is correct. However, here I believe the intention is to use the noun "Artists" as an adjective. As one might say, "Printer Manual" (not "Printer's Manual") or, for that matter, "Bryce Forum". So the usage is acceptable. Not that I want to nitpick someone whose first language is - Romanian? - is that right? - but the phrase is "bear with me" rather than "bare with me", which would be an invitation to the nudist camp. But you did say you were way more obscene :)
