Patreon is a new site for crowdfunding that works a bit different. At Patreon, the creator asks for a small amount for each thing the creator produces or a small amount for each month.
For Traveller fans there are now three creators (that I know of) that may be of interest. Steffon Worthington is creating maps. Mostly non Traveller maps. Erin Palette wants to be paid for each blog post. Some of her posts are about Traveller. Donavan Lambertus is creating ships and other stuff for his Foreven Traveller setting.
I support Donavan Lambertus since that gives me the most Traveller value for my money.
