Hi, a friend of mine (who agrees with our values) who I referred to riseup deleted his account several months ago as he was going to switch to another email service.
He missed riseups privacy features and wanted to be invited back, however after I gave him a invite code it seemed that the username was reserved.
(I was reading about this issue here:
Is there any way you could remove the name from reservation so he can create his account?
Thanks very much-Sarah
