I got two e-mails today inviting me to join the Yahoo Group "Insightforum". Never trusting such things in e-mail, I went straight to Yahoo Groups and tried to find it -- no such animal as far as Yahoo search knows.
1. Midpeninsula Insight Discussion Forum: http://groups.yahoo.com/group/insightforum
— I don't know anything about this one.
2. Insight Forum: http://groups.yahoo.com/group/insight_forum
— Inactive since 2007
3. Insight Practice Forum: http://groups.yahoo.com/group/InsightPractice
— Very active group moderated by Jinavamsa/Mitchell Ginsburg, an American student of the Thai teacher Dhiravamsa. Its threads are pretty wide-ranging, but the focus is chiefly North American vipassanā, and especially the more eclectic and psychotherapy-oriented wing of this movement. I've been a member almost since it started, but haven't read it for ages as it's not really my cup of tea.
Khandhānaṃ rāsaṭṭhaṃ, āyatanānaṃ āyatanaṭṭhaṃ,
Dhātūnaṃ suññaṭṭhaṃ, indriyānaṃ adhipatiyaṭṭhaṃ,
Saccānaṃ tathaṭṭhaṃ aviditaṃ karotītipi ‘avijjā’.
It prevents knowing the meaning of heap in the aggregates, the meaning of actuating in the sense-bases, the meaning of voidness in the elements, the meaning of predominance in the faculties, and the meaning of suchness in the truths, thus it is called ‘ignorance’.
(Visuddhimagga XVII. 43)
