Email alias

Do you love viroids and viroid-like RNA agents as much as we do? Show it off by getting your very own email address! Email aliases are available at no cost to bona fide members of the community with research interests relevant to viroids.

These aliases are provided via ImproxMX and are only able to receive mail. Because of the third-party nature of the mail forwarding, we do not suggest receiving sensitive or important emails via an address. Instead, we suggest thinking about it like a university's alumni email forwarding system: a service to the community but probably not your #1 choice of email.


We maintain an active Slack channel that is open to anyone in the community who wishes to participate. Invitations can be solicited by sending an email to with your name and research interests.
