No need to worry the help and support from BGS is excellent. Take a look at the JALS Forum - Technical subjects area. You don't need to register to browse.

Also look at the archive to get an idea of the sorts of questions asked and the way thay have been answered.

I know Scroggs has said it many times on here, but seriously, if you use the search function on the JALS site you'll find that many of the questions you want to ask have been answered previously.
Good luck.
