Three characters on the .org in the X-for-Y shape. A4O reads as advocacy for others, access for all, or action for outcomes.
All three are mission language, and the .org is the extension the organisations using that language live on. The 4-as-for convention has become standard in nonprofit programme naming precisely because it compresses a mission statement into something that fits on a badge, a banner, and a funding application without being shortened by someone else.
Access for all is the reading with the widest application. Disability access, digital inclusion, healthcare access, legal aid. Every one of those sectors has organisations that would read this name correctly on sight.
Three characters also solves the practical problem that small organisations run into: a long name that gets abbreviated inconsistently by partners, press, and staff. Start short and nobody has to invent a nickname for you.
The name is listed. Offers welcome.
