Just so everyone knows, I block all posts coming from n4bble.com If you want to post to 313 you have to be subscribed.
I object to Nabble because their business model is based around finding E-Mail lists and archiving them without consulting the admin or users of the list. They also allow posts to lists from non-subscribers, even if the list doesn't allow non-subscribers. They say they don't but they haven't properly implemented the restriction. I also don't trust them not to harvest and re-sell e-mail addresses. I also object to them archiving 313, even though I've told them not to. It's being archived at least 2 other places, 3 if you count the raw archive files on hyperreal. I've unsubscribed their mailbot repeatedly. I shouldn't have allowed them to resubscribe in the first place, but sometimes I approve subscriptions in a hurry without scrutinizing the address. They resub every time they notice I've unsubbed them. I'm tired of their BS. So if you use Nabble to read the 313 list -- sorry, but you'll have to suck it up and learn to use and manage a mail client.
