@artsyhonker I had some training for PR writing once. From memory:
1) write 3 paragraphs, each should have at least one quote from a named party; 1st para should be catchy and give a rought idea what it's all about
2) write so that journos can easily copy-paste into an article
3) at end list at least 1 person who can give more info, with phone number
4) keep it short, simple, clear; PRs are for getting attenion, not explaining everything
