Many thanks to those that do this but I don't see any ads with the Proboards Android app anyway, and what you are not aware of doesn't remind you to chip in. I made a one month ad-free contribution once for another forum. Proboards took my money soon enough, but the ads kept a-coming. Upon investigation it turned out that only staff could actually implement what I'd paid for (OK that may have changed, but that was the case back then.) I suppose I could have contacted the staff and given a heads-up, but that would have defeated the altruistic purpose. Moreover the Proboards team have never once responded to any of my few polite enquiries. Hey-ho, s'life I guess.

That's still true, b4nj0. And I'm not sure if the main admin (user/1) receives any notifications that they have ad-free blocks available when someone else purchases them, but other administrators are definitely not notified.
We had a couple of blocks that were purchased by an anonymous user, God knows when. We weren't aware of them until stumbled across in the Admin panel in June of last year.
