Three characters on the .org, X-to-Y. O2L reads as online to local, opportunity to learning, or observation to learning.
Online to local is a genuinely useful framing. A great deal of civic, educational, and community work is about converting digital reach into physical presence: getting people from a webpage to a room. Organisations working on volunteering, local organising, and community programmes all face exactly that problem.
Opportunity to learning suits education access work, where the gap between an available programme and a student actually enrolled is the whole challenge.
The X-to-Y form gives the reader a direction to follow rather than an abbreviation to memorise, which is the difference between a name someone repeats and one they write down. For organisations that depend on word of mouth, that’s not a small thing.
Three characters, permanently scarce, correct extension.
Enquiries welcome.
