problem posting

i cant create new topics or post a reply in any section but here?

Yes, I am computer illiterate...I just joined a few days ago and I was excited to be able to post my questions. Only problem is that I don't see anything to click on to do a post. I also can't find a way to contact someone for help. Sorry about being a pain in the butt... If people can actually read this somewhere, then I guess that would mean that I did, in fact, do a post?! It's just that I had to "reply to a thread" to do it. Can anyone out there make sense of this email?!?! Please help me get from to .

I'm gonna try again because I think maybe my last post didn't show up...
If I want to post a question, do I have to find an already existing thread to post to? I posted a few days ago but then it looked like it didn't even show up. Also, is there some sort of a help desk for computer dummies? Thanks!!!
