Community management isn't easy especially as you pass the 300 member mark. And I can see it's really growing in active participants of the PYPT sessions. Mee6 is a great bot just for welcoming new members. There is an option both on it and on Dyno to send an automated private message to people who join. Those might be useful to you. I'm really hoping somebody would develop a bot that would do the work of allowing people who have upvoted and/or commented to drop their posts. It would probably be a pretty complex bot but my god it would help me out. Right now my server only prevents new members from link dropping without voting because it would just take too long to check every active member every time. I've noticed lots of servers picking up the same design and wonder if anybody has found a way to automate it yet.
