I've considered it, but I don't have the confidence to charge for what I do in any capacity. I would love to setup a donations thing for anyone that would want to do so, but I don't know the best way to go about it.
I was thinking something more in the line of personal donations and such. I can't think of anything that would work with that. Paypal only allows it if you are an "organization", which is stupid. That doesn't make sense to me.
