I dunno if any of you guys know Liz Finnegan (perhaps best known as a former editor of The Escapist) but she's now working for Stack Up, a charity seeking to improve the mental health of military servicemen, both current and ex.
She's close to her final goal (just $500 left of her $30,000 target).
Because of site rules, I don't believe I can talk about the milestones, so you'll have to check out the page yourself for them, but I will say that I am in no way affiliated with this fundraiser or the charity, nor Liz herself, save from a small handful of tweets.
