What do YOU offer for "donating"?

[Fireproof]

I couldn't find a general discussion on this. If it's been discussed, please show me the way.

I'm curious as to what people have chosen to offer members for donating or paypal payment. For example, it would be nice to have a set of features that you can only have access to if you donate $20.

I'm not too creative and would love to be able to leverage your experience/suggestions. I also don't yet know what all is possible. For example, I thought about giving 5x the PM space for those that donate, although I don't know how that's implemented. I'm guessing I would put them in a "paid" group or something where I can tweak their settings/permissions? Access to certain forums is another idea.

But what are some creative ways to encourage COMMUNITY and also donations, without turning people off??
