I've created a new website, ALAN'S LIST of POLYAMORY EVENTS:http://polyevents.blogspot.com
These are all the major poly cons, festivals, gatherings, etc. coming up in the next 12 months, as far as I know. I think the list is pretty complete, at least for the English-speaking world. There are now 13 events on the list through July 2012 -- with descriptions and sometimes my commentary when I've been to one of these or know people who have.
ALSO: At the bottom of the page are five resource lists of LOCAL POLY GROUPS worldwide, sorted by location -- making it easy to find the local group(s) in your backyard, with their own meetings and happenings.
Instructions for how to suggest new listings are on the page.
I intend to keep the site updated and current forever. (I hope I've got another 30 good years ahead, and before I go I'll try to hand off the job to someone else.)
Please link to this and pass it on.
This project is an outgrowth of my other site, POLYAMORY IN THE NEWS:http://polyinthemedia.blogspot.com
... which I've been running for six years now.
