I'm not online a lot, and neither are the other current admins.
If we could get one or two members who are online at least once a week or so to send the group a message saying they'd be willing to help out, that would be lovely (especially as spring approaches in the northern hemisphere!)
Be a decently well-versed weather spotter. I like (and, I think visitors appreciate) the submissions being in correct folders, organized by storm feature/type. Submissions are voted on/accepted or rejected when they're submitted properly or improperly. Admins kindly ask the submitter to resubmit when the item has been incorrectly submitted to the wrong folder. You'll need to be able to tell the difference between things.
Be a decent judge of photos per the group rules. If it is a weather pic but doesn't quite fit the rules, it goes into the group favorites. If it fits the group rules...into the correct group gallery folder it goes!
Be online at least once a week. I'm going to try to be better about this as the season ramps up. I've been busy, but I'll try to do better.
Don't cause drama or you'll get the boot! Practice courtesy and understanding.
Also, pardon if this has typos. It's late, I'll proofread later...
