Open Collective is a platform for transparent fundraising and expenses for projects like TiddlyWiki. It is the official TiddlyWiki community fundraising space.

You can make a fixed one-time donation, or setup a recurring contribution.
The main goals listed for donations are to cover basic costs for community infrastructure like the Discourse forum, and a new goal for supporting the TiddlyWiki Core.
Additionally, the community can make use of the platform for special projects - to pool funds to pay for development, design, or anything else. The File Upload Plugin is the first of these, and we want to welcome others to launch projects here.
