is it posible to have a disscussion with 100 + responses ...?

The most important thing about starting a discussion is the underlying point that it intends to bring out in the open . One more important thing is the way in which one can relate the discussion with himself in his life and then respond. This will certainly be a good discussion and may inturn bring the responses you are looking for.

I think the most I've ever seen has been around 60.

ya...of courus...as long as your discussion is wonderful enough~~~~~~~~and it will absolutly popular
