Good idea, though perhaps you should also ask about interest from those who do speak greek, maybe some come here just to practice their english and would not be interested in a Greek Language Forum, or perhaps some who are competant with greek do not want to be bothered trying to follow in depth theological discussions. Ultimately though, it's hard to judge how successful it will be without actually implementing it; though I suspect it will be more popular than the Russian forum, I dont know how much so.
