Where is going l2jserver?
The devolpers not are a dedicated devolpers (Theys have job I guess).
So, i think in rework l2jserver by 1 U$D (Just an random number) per month and get access to SVN.
Why this gonna work?
I guess (Please some admin put in this post the user count per month in the SVN) 100 Users minimun per month. So 1U$D for 100 Users.
Why not free?
If you cant pay 1 dollar per month, how you want to get an server? (A nice one

Where are the good part?
So, whit the money per month. L2JServer can pay admins to devolp it full time (Like 8 Hours per day), and fix any bug in a moment.
Why this is better to apply?
I think, Zoey96, MERLIX, Unaffrid (L2JServer devolpers than work for free) dont gonna to live for ever then l2jserver need new devolpers and whit money its more easy to get once.
And an demo version for students (Not fully working, just an java part).
That is just an idea (Crazy One) for L2JServer Devolpers.
