If you haven't seen your Sakai mail for the past few days, you're going to see that about 1/2 the email on the lists are pleas from former subscribers to be removed from the list. At first they were comical but I have to admit they are starting to grate on my nerves!
If you are still in need of unsubscription, Seth Theriault posted options for unsubscribing that can be found at http://thread.gmane.org/gmane.comp.cms.sakai.devel/29319
Some suggestions to the foundation for any future changes to systems that are critical
1) Tell us exactly what is going to happen and with sufficient notice. I'd suggest at least a 24 hour lead time. With this notice you'd be able to get volunteers to assist in confirmation that things are working swell.
2) Please don't make changes at 10am on a weekday. I know this is a global project but 10am is a time that impacts a large portion of our community. When thing go awry (and we all know they often do), it'd be better to impact a smaller population
3) When there is a problem, have someone from the foundation tell us you know there is a problem, what it is, ect . .
That said, I'm sincerely happy that something was done to address the problems we were having with the lists on collab. As a community we had been crippled and are now able to communicate to make progress in an open manner. Further, the messages are now nicely tagged by audience.
