Now that I think I understand your role, here are a few more suggestions:
1. Double XP Weekend
- XP (from mob kills)
- AXP (from mob kills)
2. Battlestation Double VP Weekend: This can be done by level range such that you're sorta rotating which battlestation range gets double VP. It might, at least, encourage a greater level of participation in that battlestation range during the double vp day(s)
3. In Game Scavenger Hunt: Give participants a clue that'll lead them to a NPC who will give them the next clue.. all the way to the end. Can be done in a variety of different ways including having seperate events on RK versus SL. Have prizes for the first 3 people to complete and a generic prize for everyone that completes within a given timeframe.
4. Webchat with a dev: One of those moderated talks where one of the devs is broadcasting and live answering questions from players. Something that lasts 60-90 minutes would be nice and, if necessary, questions could be submitted in advance.
5. SL storyline events. I don't know enough about AO's RP to suggest something specific but it would be nice if there were some RP events in shadowlands. It seems like everything that happens takes place in one of the main cities of RK. Is nothing happening in SL or the Outzones?
6. I really am not sure if this idea is out of your bounds but.. how about a NPC creation contest. The focus of the NPC dialog would be teaching skills to new players. Players would design a dialog that teaches new players profession based skills. Winners would get a NPC placed in game with this dialogue as well as getting to choose the NPC's name and outward appearance (yes, this is my evil plan for getting a NPC in game named Traderjill!)
Feedback: There was a burger ingredients contest that took place not so long ago. We have burger stands all over the place, it would be neat if the winners had their burgers placed in game with the actual recipe and creator's name as part of the item description.
