From The Mana World
Before developers release game content onto the official server, they'd like feedback from other developers and playtesters. This testing server regularly restarts for content fixes and tweaks.
IRC
Those interested in content testing should come to irc.themanaworld.org channel: #tmw-dev.
Gitorious
Keep track of our testing phase by following us on gitorious.org: Server-data, client-data.
Forums
Before content is tested and/or while it is being tested, content is often discussed on the tmwAthena development forums.
Client
Those interested in playtesting need to get a client, which can be found on our downloads page.
Location
Our server is located at 69.162.134.30 port 6901.
