Hi Kevin,
Welcome and thanks for running a Tor relay! :)
Feel free to subscribe to the Tor Weather service [1] if you have not done it already. It will warn you if it detect anything problematic with your relay.
Kevin C. Krinke:
I want to help more. What services (other than Tor) can I host? What else is needed in the general community?
I think it's best to have your server fully dedicated to run a relay. But if you have other systems and enough bandwidth, hosting a Tor mirror [2] or a Tails mirror [3] is also a good way to help! :)
