Forum Moderators: rogerd
The common consensus was that existing members enjoy "our group" because it stays on topic and has no cliques:
The most knowledgeable on the topic gets the most attention. The topic is not related to spelling/grammar... so no extra points for this.
Ideas are shared freely... it doesn't matter who posts the new idea, new member or senior member. New ideas are welcomed and built upon.
Everyone is treated equally -based on their knowledge of the forum topic- ... actually, that sums it up.
Luck is also involved. I happened to learn about an artsy type technique that was emerging in other countries, so decided to start a "hub" site. Everyone who knows about, or wants to learn about, the subject is welcome.
What I've found is that if you set a consistent tone for a period of time in a forum, you have relatively few problems - even most new arrivals grasp your expectations if they have read a bit before posting.
About the only issue becomes mob moderation when a new arrival commits some kind of transgression and six old-timers berate him/her for it. That's a credit to the standards of the forum in one respect, but not necessarily the best way to welcome a new arrival.
Consistency is really important. People will follow the rules if they perceive that everyone else is doing the same, and that violators are dealt with.
