You changed it since I was last there

(And it wasn't that long back)...
WoW that looks great!.. Just a couple of questions though..
php5? Will that mean that sys admins have to upgrade the php package from 4 to 5?
MYSQL? Again upgrade from 4 to 5?
New Features:
Integrated friends list and private messaging. <- Could this not be implemented as a minor release first? I notice in the svn that 1.3 is already there and assume as such that you were working on it? I think it would be a good idea to get this functioning and then when LT 2.0 comes out it can be more easily integrated with the new google maps feature. (From a user point of view?) It also means that community building can be built on now so that when all the new features are finally implemented there will already be a strong community in place to avail of them.
I like the idea of cleaning up the user interface (I take it this is the admin area?) - I'm going to check out the repository later to night to have a look at it - Will need to set up my local 'LAMP' server first....
