Unfortunately, I am unable to answer questions about general relativity itself; there just isn't time. However, you shouldn't be asking me, anyway; you should be participating in an online discussion forum, where there will be several people to ask and others might have the same questions. The best such forum is the newsgroup:
sci.physics.researchThis is a moderated discussion forum, full of people who really know what they're talking about (although you shouldn't be reluctant to ask beginner's questions). It is a usenet newsgroup, but the link given here is directly to the Google version, which is immediately accessible without any prior usenet experience. (More about s.p.r.) Other relevant newsgroups include:
sci.physicsThese can be useful, but they are not moderated; you are at least as likely to find someone who thinks Einstein was a misguided crank as you are to find an expert in relativity. In addition to these newsgroups, there is a discussion forum at superstringtheory.com:
superstringtheory.com discussion forumThe name notwithstanding, there are plenty of discussions about relativity, particle physics, and cosmology, in addition to string theory. There is also a general relativity board at Physics Forums:
