Here's an idea. Just an idea. Please don't execute until dvsDave gives his approval/opinions.
Everyone, click "Members List". Then click "Posts" and then go to the last few pages to find members with >10 posts. Pick a member at random, probably best if it's one who has joined relatively recently. Read their profile, and send them a message, best if they allow email, saying "Hi, I'm GeorgeSpelvin from Control Booth and I noticed you joined on [date] and posted X times about YYY. Haven't seen you posting on CB recently, just wanted to see if you're still interested in tech theatre..." The more customized the message, the more likely that inactive, under-posting member will be likely to respond. Use some of our many Welcome phrases, such as "Ask what you want, answer what you can," "Control Booth is what the members make of it" "We're a friendly and goofy community, always willing to help," etc. DON'T scare them off by mentioning pirates, voltage, eating animals, or other non-theatre issues.
Dave, too pushy? Not worth the effort? Anyone, ideas?
On another note, one of my co-workers whom I tried to get to join, said "I went to CB and looked around, and all I saw was people arguing." Not sure how to take that, and not sure what specific threads he was reading. I think the regulars are pretty good about waiting until the OP's question is answered before getting silly or hi-jacking, but maybe we should attempt to curtail that just a little? Again, opinions from everyone?
Also, I recently discovered the "inactive" list consists of members who haven't posted in 45 days. Perhaps a way to segregate those users, and/or a threatening message "if you don't post within 30 more days you will be dropped and will have to re-register." I don't want to encourage useless posts, but do want to make us lean and mean. Maybe it's the anal-retentive control-freak in me...
Just a bunch of random thoughts, looking forward to hearing Dave's, and other's, opinions.
