I saw on the bulletin board that website design classes are going to be offered at the community center. I’m really interested in taking the classes. Is it O.K. that I don’t have a membership with the community center? I don’t really have much experience. in this type of thing though, so I hope there are different levels because I will probably need to be in the beginner class. I’m just a basic user.., you know, e-mail and the Internet is pretty much what I’m familiar with. I also didn’t see any class dates or times listed really hope the class will fit into my schedule. I know classes are usually free at the community center, but 1 didn’t see anything mentioned .about prices either, so can I assume that it’s free? I’m really interested in the class. My phone number is 289-2910. Or you can e-mail me at jtimbers@speednet.com. Thanks.
