Welcome.
The captcha's are a bit annoying, but it's worth it because the people here are great.
One tip - If the captcha just sends you back to an empty page, just quickly click 'back' on your browser twice. The post that you typed out will be recovered, so you don't have to type it all out again. I usually find that the second attempt to post always goes fine - it's just the first time that I get the blank page thing.
