Giles Williams, the programmer who started development of Oolite, the freeware multi-platform Elite play-alike, is suffering from Myasthenia Gravis, a fairly nasty condition which affects his stamina (amongst other things), which is unfortunate because one of his other interests is cycling. He's launched an appeal to get money to buy an electric bike, which will help him to get out and about. So far he's raised £360 of £600 on gofundme, including some donations sent by people like me who prefer to use Paypal. Details of the appeal are here:

I'd rather not post his email address here, but you can find it on the Oolite forums if you're interested in sending money directly:
