eh, well, as someone who flatmemes, I feel like the part about warnings deserves a bit of a caveat. We've got a few people who like to round robin things, particularly extremely kinky things (lately of the Matt/Frank variety). Which, to be clear, isn't a problem at all, but those little bits can and do show up scattered around flatmeme with no warnings because they're usually only, like, three sentences long. So you take your chances if that kind of stuff, just for example, is not your cup of tea.
