It turns out that invite codes can only be used once. Also, riseup may not be a good choice. Their website says that they're way behind on their email deliveries, and AOL is blocking mail from riseup. In addition, riseup has a 'politically correct' usage policy that you may or may not approve of. Although their sentiments seem sensible, to me at least, I'm uncomfortable with the idea of equating 'some of the left' with 'the good', seeking to inhibit expression by others, and inhibiting dialog across social divisions. From their website: Solidarity: riseup.net affirms common cause and solidarity with a broad spectrum of the political left. However, there are some things which we cannot support. We ask that you do not use riseup.net services to advocate any of the following: * Support for capitalism, domination, or hierarchy. * The idea that class oppression supersedes race or gender oppression. * A vanguard strategy for revolution. * Population control. In any case, if anyone is interested in getting a riseup email account, let me know and I'll send you an invite code. I've got four on hand already, and their website says nothing about a limit. rkm
