First, you don't make it very easy to find your donation button. (FAQ > How can I contribute?)

Second, the button doesn't work! The form submit button appears outside of the form tag.

I use MapTool every week when I run my campaign and often a few times before setting things up.

I would like to make a (small) but recurring donation towards hosting costs, development expenses, etc.

It's something we've discussed. I think everyone's on board with getting the donate button going again.

We've also discussed getting a Drive Thru RPG and Amazon affiliate link so you can buy what you're going to buy but donate to RPTools at the same time with no additional cost to you.
