This week I stumbled upon RU as an alternative (with the self hosting option!!! Great!) to [censored] and I really like it. I would also like to see RU Server running on Linux, even it just has the basic functionality like the Relay option (which is what I intent to use it for). My whole server park is running on CentOS and I really would like to keep it like that, but for now there is no other way that to add a Windows server to it :-( .
Please consider creating RU Server for Linux.
