Eric,
Thank you for bringing this up. I don't have a designated Paypal account for GreenHybrid because I have not yet prepared for donations. However, I do have one for SiteSpin (my dev company) as well as a credit card merchant account. The one thing that concerns me with donations is that there isn't any expense that this site currently has, forgetting $8/yr for the domain. For this reason, I'd basically have your donation sitting in my own account and unless the community decides on something they'd like for the money in the budget, your donation will essentially be payment for my work here! Humorous, yes, but I'm trying to be honest and at this point the main concern is not profit. Right now building a strong network is priority one.
So, what this ultimately comes down to is: is a donation to the "Jason worked hard on GreenHybrid" fund what you'd like to support?
