Greetings and welcome to the watercooler
A must read thread is the
newbie guide, which is in a sticky thread at the top of the Newbie Forum. Also check out Cathy_C's thread, which is also stickied at the top of the Newbie forum,
Next on our tour, if you'll look to the left, you'll notice... to find out about the various buttons and icons, and also about rep points, how to PM (private message) members, custom avatars and a whole host of other useful stuff,
If you have any problems you can PM (private message) me and I'll see if I can help, or you can post in the Super-Dooper Newbie 'Ask the Mod' thread at the top of the newbie forum.
And for fun, we have the terrific Newbie Question of the Day thread. Pop in and have a go at answering a few of the really easy questions (the link is in the sig line below). They are easy. Yep, they are. And so much fun.
