I will contribute to both the review-a-day and the coding snack.
I had a few ideas:
1. "Who gives a buck about DC?" whereby every member vows to donate at least $1, and earns a badge.
2. Sponsor a DC-er to do something crazy. Zany members offer to maybe get photographed dressed as Cody in the mall, or go to work in a silly hat or have a cody "tattoo" if a certain fundraiser target is met.
And one general suggestion:
An ".... of the month" round-up. This can be purely subjective, but a small round-up of the forum's activity would interest me greatly. For example: "Topic of the Month" ~ "Rant of the Month" ~ "New Software Release of the Month" ~ etc.
My favourite: "Member of the Month" to celebtrate a DC-er who's been particularly helpful, or released something really good, or even ironically celebrate someone who just got on everybody's nerves...
