Morning all, Thanks for all the responses yesterday. I think the clue was in the fact that I didn't even manage to spell "idiot" properly. I really am one! I'm not a whole heap further forward on the "why" question. Do Facebook have sales tools that say what the benefits of their system are? I hear the comments on Facebook Mobile, that will simplify the screen but doesn't turn the language in to English. What is a "wall", what is it for? How do I send a 1:1 message, or a broadcast to all my friends, and how do I make sure it doesn't go to the whole world? How do I join in chats with strangers on topics that interest me? Or maybe that should read can I join in discussions with strangers? Like I say, idiot is being too kind to myself. Barry, I'm afraid I was lost by about the second line of your answer. But let's start by asking what Aim is, and what is it for? Frank, yes, my physical prowess exceeds my intellectual at this stage, though that does not say a lot. I'm off to London at the weekend. It would be great to contact others affected by RP. How do I do that? The only group I'm in sent me an invite, so joining was easy. My 2 friends also sent me invites, I haven't managed to invite any friends to join me. Tried once, didn't manage it. Any help there? How do I know if my friends (real ones) have Facebook accounts to link up with? OK, enough questions for now. Like I say, an idiott's guide would be a great help. They have been written for many other applications, is there really nothing for Facebook, or social networking in general? Maybe it's an age thing, if you are the right age for Facebook, you are the wrong age for idiot's guides! Sorry for the long post. I am willing, but struggling.
