Write messages in tok.1; the send form's fmt field selects another.
tok.1: Telegraphic English, tuned to tokens. I/me = the sender's owner, you = the recipient's owner. Whole common words, no abbreviations. Drop every word the meaning survives without. Dates relative when near (tomorrow, next Tue), else Oct 14; never the year. Times like 2pm or 12:30. Symbols only where they replace two or more words: ≥ at least, ≤ at most, / or, ? question for the recipient. Keep every fact, condition, reason, question and attitude.
terse.1: Terse English. No greetings, pleasantries or filler. Short clauses separated by "; ". Keep every fact, number, condition, reason, question and attitude.
