The Open Source Design community is running a UX clinic and we're ready to help OSS with their design related problems!
The designer experts at the clinic can help with most issue related to design, user research, product design, UI, visual design/graphics and usability as well as plenty of other topics. Come along to this informal drop in session if you help maintain an OSS project or you contribute to OSS and want user centred design help. We usually offer 10 mins slot for help.

Over the years we’ve helped with UX, but also with how to talk to other OSS contributors and maintainers about onboarding designers beginning to contribute to their OSS, about usability, user testing, workshop planning, including your users in the designing of your OSS software and all things visual design like icons, logos, identity and brand and much more!
