Is there a way to make a one-time donation without giving up my life-time membership? I love that the creator is doing this. There are so many services that I would have paid for, but instead they got shutdown or turned into crap. I was going to convert immediately, but the thing that gave me pause was "if you are getting more than $1.80/month of value". It's not clear to me that I do. Not because the service is bad. I've not had issues with downtime, and I think it's a fair price. But I don't know if I, personally, use it enough to get that much value out of it.
