"Individual Engagement Grants support Wikimedians to complete projects that benefit the Wikimedia movement, lead to online impact, or otherwise serve our mission, community, and strategic priorities.
"We fund individuals or small teams to build, organize, pilot, create, improve, research or facilitate something that enhances the work of Wikimedia's volunteers and helps us achieve our vision of a world in which every single human being can freely share in the sum of all knowledge."
The deadline for the current round is Feb 15 24:00 UTC, which is about 26 hours from when I send this. Proposals for the next round will open in August.
Please also consider helping discuss current proposals between now and 22 February: https://meta.wikimedia.org/wiki/Grants:IEG#ieg-reviewing
"Open discussion and evaluation of proposals is intended to encourage diversity and innovation in the grants made, by bringing multiple perspectives to the selection process. Funding limits the amount of Individual Engagement Grants we are able to make in each round, and proposals are carefully evaluated and selected according to pre-determined criteria https://meta.wikimedia.org/wiki/Grants:IEG#ieg-criteria."
Hope this is of interest!
