OtherWorlds: How Do You Want to Do This?

[st_aff]

I'd like to run our first OtherWorlds event in March. My questions for you:

1. When in March is best for people, assuming it'll run 10 calendar days for the characters? Remember, the idea of these is to get these stories told and their threads finished within the month.
2. Who is interested in a voice-chat adventure on a Sunday during that period? 
3. What general kind of world are people most interested in going to for this first event? Keep in mind, these will not be worlds that any characters do (or could) come from.
4. What kind of stuff do you want the characters to be able to do in this first world? 

If you have questions for me, comments, a burning desire to run a particular kind of event yourself, anything, fire away.
