I think it'd be a good idea if you created an 'entertainment' forum with like 'books' 'tv' and 'movies' subforums for us to chat about our favorite novels, series, shows, and films! That would be so amazing if I could find another Christian who loves Adventure Time and My Little Pony and Hunger Games and anime and manga <3 *rant*
A contest would be fun. Or even a secret santa, too bad Christmas passed :'[ We could have an Easter event and a Valentine's Day event! and for each season, you could create a forum for us to talk about our traditions and plans. That would be fun as well!
A meeting time could be hard. but we could do it.
Maybe we could have a home-group type idea. Where we all split up into groups with a leader that leads them. Or maybe the leader could change each week. They could share a verse or a Bible story to learn from, then we could all share about our week, and we could pray for each other. You could make a forum called 'homegroups' or something, and then subforums for each group. Meetings could be weekly, and could last all week, or everyone could meet at a specific time. Each group could have a different meeting time, whatever worked best for everyone. :]
I hope I helped, if you need clarification on any of my ideas, please ask! I love that you're wanting improvement for the guild and am looking forward to being actively involved with our sisters <3
