You should categorise the thread you post based on the main topic the thread revolves around. In this case, I think the main topic would be
IRL get together, so this topic would belong more in the
Lounge rather than the
Dares section. Though, if you want to create a group that gives dares to each other and that it's optional to get together IRL, then the main topic would be daring each other, thus it belongs in the
Dares section.
By the way, if you are looking for a more serious get together involving BDSM and such. Then you could post it in the
s/M Lounge rather than the
normal lounge.
