If you don't have to give support and don't want to, what is the point of being on here then?
That statement in itself shows your complete ignorance for what we do here.
phpBB is an opensource organisation supported entirely by the community. Team members have official status within the organisation and assist the community in various ways. Support is only offered via the board; we do not advertise or provide official support via IM/PM/email/telephone or any other private means.
When you ask a question in the Support Forum, it allows anyone who is currently free to answer it. This does not mean that every team member will instantaneously flock to the question. Answers provided in public can also be referenced later and located via the search feature; questions answered in private cannot.
As an organisation, it is up to us to decide how support is provided. It's certainly not up to you to question who should be doing what or what the "point" of being a team member is. You are welcome to PM me if you have further suggestions.
