...To split the sub-forum into sections?
At the minute, it's just one room isn't it. It might become a bit of a jumble if we've got a mix of everything in one room.
If it's possible to split the sub-forum into two rooms, we could have one room for posting photos only, and one room for discussion only. That way, people know what's what and it's not all just one big room full of randomness.
