You're welcome, and thank you! No, I'm not aiming to be a moderator. In order to become a moderator you've to apply for it on ATA's web site and I don't think you can become moderator by just answering questions.
Well if you have applied then it does depend on what kind of questions you answer. If you show you have good understanding of the ToU then you in theory have the potential to become a moderator.
