I know Gaz wants to keep it all-Marvel related and I get that. However, sometimes there just isn't anything game related that folks want to talk about but there is something non-game related that they do want to talk about. (Robin Williams' passing is the perfect example.)
People have created various types of bonds with others and they like the environment here. They want to discuss various topics with the people they have met and know from here. I may want to hear @Vinceness opinion on the latest TMNT movie, or maybe @Quintessence wants to start a discussion of and get people's input on his latest tattoo.
Many folks don't interact with each other outside of this environment but still have other common interests. I think an Off-Topic forum would be a nice addition.
