If you're able/comfortable, please consider setting up a recurring donation. For long-term planning reasons, it's helpful for organizations to have a consistent recurring revenue stream that they can use to project assets further into the future. One-off donations are good, too! But if you're going to consistently send them money anyway, you may as well do it in a predictable manner to help their accounting.
Another chance to upvote the donation link to top thread on an IA story since a direct submission got swallowed by the dupe detector! They are doing such much amazing things.
Your Donation Will Be Matched 2-to-1! [...] Right now, we have a 2-to-1 Matching Gift Campaign, tripling the impact of every donation. (from the home page)
Somehow it's the IA's job to fix problems that we all know are problems, sadly.
