Brilliant feature! Thanks so much to Rich and the lot, as always, for your hard work on this. At first I thought you meant it sent invites to everyone on our Steam friends list (which is a few hundred; that would be too much haha.) Having this for on-site use is great. In any case, I'll be spreading the word and inviting any of my Steam friends that I know are into achievements to the site. You know, the cool ones.
