I certainly don't do this enough, but I want to urge everyone who benefits from this site to visit the folks responsible for keeping it going, financially.
The good folks at Roll20.net have been donating a substantial amount each month for the last few years. Without that donation, I would have long ago needed to resort to a subscription only service. I was about to do that when Roll20 stepped up and made the offer years ago.
I am forever grateful to them for their extreme generosity. The only thing they have asked for in return is that I keep the site going. I hope I have lived up to their expectations.
So please, let them know you appreciate their sponsorship, by visiting their site, and sending them a thank you note. Or, better yet, subscribe to their excellent services.
