Thanks to reader Gabriel, who sent this link to a Facebook page (it's public; no need to be a Facebook member) which allows posting of resignations (specifically, mass resignations). Here's what he says.

I would just like to raise awareness to everyone and the site's webmaster that I've recently set up a dedicated Facebook page to chronicle the mass resignations. Please visit and spread the page far and wide! :) It's a public page, so anyone can visit, even those without a Facebook profile.

Here's the link to that page.
