Could you use an extra 45,000 per week?
If so, you might want to consider having a subscription object written for you in Second Life.
A “bonus” called an allowance is issued in Second Life every week to residents. It’s L50, or roughly US0.18 per avatar.
18 cents doesn’t sound like much, but hire a developer to create a script for your cause and ask people to donate their L50 every week to your cause. A quarter million Second Life residents would be US$45,000 per week. Not too shabby!
