We're currently working on the Beta Client, it will be available later this week.
For those interested in participating in the Beta, you'll have to personally contact an Administrator to gain access to it.
Only members with the "Beta" rank will be allowed to log in.
Please note that if you ask for the Beta, we hope that you're actually helping prepare the server for the launch by testing and finding potential bugs that need fixing.
More information regarding the Beta will be announced in the upcoming days.
