They most certainly do soddy, some know each other in the 3D world and others like myself have met few others in person but have developed good friendships outside Mudcat. Hearme can also be interesting as you get to hear other catters and also exchange a bit of chat - sort of opens up a new dimension...As regards the tongue in cheek remarks, the use of an emote icon such as ;-) or an indication such as *BG* can help to avoid missunderstandings.
