Welcome to the Q&A Forum

I just joined Moz and am trying to use the tools however, when I attempt to do so every link comes to a that only allows me access to post questions here. If anyone can tell me what tool is best to find reasons google has not indexed my site, I would greatly appreciate the help. Also if anyone knows why I am keep getting routed to this forum when I try to use any of the tools, I would also appreciate help with this. So far Moz is very frustrating.
