I'm contemplating having some people do moderating on my forums, and just was hoping to spark up a conversation here on other people's experiences in doing this. I've talked to some of the people about this, and have kind of pre-selected people to be moderators. Also, some people have made themselves into good candidates for this by being very useful and participating a lot in my forums. Any pointers?
You seem to already be on the right track by lining up your candidates as the people who are leaders on your forums.
You want to put together a set of moderator guidelines, which state what is expected of a moderator, what the ideal qualities are. You will want to make sure that they understand how to use the forum software and the moderator functions, once you promote them.
Besides that, be fair, be honest and be appreciative of their time.
Pre-selecting members is okay ... but the best way is to select mature, knowledgeable, and regular posters on your forum. I'm not sure if you meant you are already doing that, but I thought I'd get the point across. Patrick's suggestion is a good one -- make sure you have guidelines drafted up first and that your moderators are familiar with them. Good luck!
