There are no right or wrong answers. They're meant to help you more fully investigate your goals. I see you active on here and on TAZ, so I'd like to help you while also serving as an example for other beginning admins.I don't know whether i got the questions right but here are my answers.
1) To learn the basic of how and what needs to be done to become a great webmaster.
2) As of now there is no best-in-class content offered in the forum, but i feel the reply and good support given by fellow users is best for new users.
3) Short term goal is to make the my forum known to fellow webmasters and make them sign up and for the long term goal i don't have one.
4) When users join and actively participate and the popularity of the forum reaches wider audience that defines growth for me.
