Three characters on the .org in the X-for-Y form. M4K reads as music for kids, meals for kids, or mentoring for kids, and the K-as-kids reading is well established in programme naming.
Children’s charities and education programmes use this construction constantly, because it states the mission in the shortest possible space and fits on everything from a T-shirt to a grant application. A funder reading M4K will understand it before reading the strapline.
There’s a technical reading too, where K stands for Kubernetes or for thousand, giving the name a home in infrastructure if a buyer prefers that direction.
The .org is essential for the charitable reading and harmless for the technical one. Three characters means the name fits alongside partner logos, on printed materials, and in an email address people type correctly first time, which for a small organisation matters more than it sounds.
Enquiries welcome.
