Thanks for suggesting but as I mentioned above, we don't have enough free time to rewrite our own source from scratch, we will most likely use the latest rewritten WvsBeta source (the one that wasn't public) because it's structure is good and the base is pretty neat.
We will most likely jump straight to v0.03 or something.
Writing a source from scratch (how tempting it is, believe me - it really is) requires lots of time and work, we currently don't have the time to put in it and if we would still go with it - it will take us a year due to not having enough free time to work on it.
Some of us have university project that require lots of time so that's why we don't have enough time for that at the moment.
A clarification, neither of us - the staff and developers, interested in making this server so we could be GMs/Admins and so on, the only motive it because we really want to play the old MapleGlobal, chances are we will recruit GMs and moderators once we get to production stage and let them handle the community instead of us doing it.
We still recruit more developers, anyone interested can simply PM me to apply.
EDIT
By the way Gil, this may be useful for you as you like to develop old versions and the original thread is no longer available.
