I thought it could be a good idea to have a dedicated thread for any worthy projects that members who are not participating in paid-for signature campaigns could advertise in their signatures.

It could be anything from charities (preferably those accepting bitcoins), informational websites, community initiatives (e.g. Pizza Day contest topic), raising awareness of certain issues (e.g. the Ross Ulbricht case) etc.

If anyone has anything, please post it here - include a link (if applicable) and a short description.
Of course, any ready-to-use signature code would be ideal, but if (like me) you don't have the skills to design such, you can post it without it. Maybe members who are in the signature design business could create signatures to showcase their skills and advertise their services.

The idea might not get much traction, but I think it's worth a try.

p.s. If Meta is not the right board for this - mods please move it.
p.s.2 If a similar thread already exists, please send a link and I'll lock this one.

Edit: As correctly pointed out by examples, some of the below do not technically fit the definition of "non-profit", but I still decided to add them in as I think they provide value and/or important service to the community. I may review this approach later on if this becomes an issue.

Edit: Thanks for all the suggestions! Keep them coming.
If anyone has any ideas for a projects/initiatives worth promoting, feel free to post them in this thread. Zwei has kindly offered his help in creating/designing signatures for free.
