How to get the players to pay for your playerworld:
1. have a world the people want to play
2. have a checking account, and an email account, and a website (even a free website from angelfire or tripod)
3. go to
www.paypayl.com
4. hook paypal up to your checking account (takes a few days to poecess but its free)
5. make a donation page with paypal's utilities (free)
6. put the donation code on your web site somewhere
7. tell pepople, ie. in the server message, or in a timeout
every few minutes in a system npc, to please visit your donation
page and send whatever amount of money they want to help
support your server. (openurl is nice here)
when you get money in paypal, you can send it to your checking
account for free.
but remember that people are not likely to give money to a crappy server, mean or corrupt admins, or to supoprt hackerville.
so make an environment that people can have a sense of virtual ownership and community in.
