As a fairly new Member myself, I have to say that the previous posts are absolutely correct - Read this board! I don't get to post as often as I might like (quiet time is rare with a little one!), but I always try to read the boards every few weeks or so. The advice that the posters here have is invaluable.
Also, one of the previous posters is correct that you should get the name of the person you spoke to in member services. Making them repeat back to you everything you asked for is a good idea too. They are a pretty great bunch, but they are human, and can make the odd mistake just like the rest of us. Just take the time to double check, and that way you won't have any problems.
Most important - Enjoy yourself! You have the next 40 years to use your membership, so take the time to do the little things that you never seem to have the time to do.
Congratulations, and I sure hope you enjoy your membership as much as we do!
