I agree with the sentiment. However, I disagree with advertising Epsilon as a brand new server--it really isn't. We have already advertised ourselves to /r/wowservers in the past, and we are even mentioned in its sticky and have an entry in the associated dkp website, which is how several people have found us.
I think it's a good idea if we make a thread to time with the release of 735.4, but I'm not sure which locations are proper other than /r/wowservers. I also don't see Argent Dawn and Moonguard as threats--a lot of people who join Epsilon come from there, as I ask each and every single person how they found us and what community they hail from. It appears our name circulates across multiple guilds and communities in both servers, and that's pretty much all we can hope for in that regard beyond making WoW accounts and starting to advertise in Pornshire (no thank you).
I also second the subject of welcoming new players. It is a very difficult transition to make if you've never played on this type of server before, and many roleplayers who have heard of phase-based servers lambast it as a ridiculous premise. Our primary objective should be to educate players on the differences that can be found between streamlined narrative RP servers, whether GM or not, and phase-based RP servers. Our server is more like Reddit, a place to host private servers (phases) that each act as more like a campaign with a central theme, so that each can coexist. Much of people's annoyance with streamlined RP servers is that characters are developed for years and people refuse to part with them, even under epic circumstances, or try to bring them back. It is less common here as characters are, inherently, throwaway, and are more similar to a D&D campaign rather than some kind of personification you must protect at all costs.
