Illarion.org

I recently (Sometime in february) donated money to the illarion fund. How do I go about setting up the illa-email?

Don't take my word for being set in stone, but I don't think that a one-time donation qualifies for your own @illarion-alias.
As far as I know this is a benefit of the "Illarion society support membership", at least it is listed there.

Otherwise the contact for such things is Alatar.

Even if I donated enough for six years of membership?
