Some advice for you, coming from someone who has already started and has been running an online
DH group for 7 or so months now:
1: Use
Skype. It's better (In all respects) than msn, and you can download a Dice roller addon for it. (The addon is extremely temperamental though) Personally, we use text chat rather than a webcam or mike, but if your players are comfortable with either of those, then go ahead. I find text chat does make it easier to
RP descriptively though.
2. Players you find on the internet will not always stick around. There will be Real Life issues, and there will be dropouts. Unless you have a good system for dealing with these, you can expect your campaign to falter as people don't turn up. This is especially devastating with small groups.
3. If your group grows beyond 5 people, split it into two games. This makes things easier to manage and helps with availability issues.
4. If you don't manage to find players (My group probably has many of the Dakkanaut ones), then send me a
PM and I'll see if you can join the next game that runs in my group.
If you have any more questions, post them here or
PM me.
For more players, post an advert in
this thread. Note, posting there didn't get me any, but then, I already have a good, stable group.
