I'm not really into AMXX scripting anymore, so this plugin is more or less discontinued.
If anyone would want to restart the project: you're more than welcome if you have to needed experience.
The SQL version of this plugin is fucked up, because it relies on other plugins that were only available on my own server (on which the ranking system worked great, by the way ;)). That would be the first issue to iron out.
If you want to continue the project; the latest version can be found on
my SVN (user and pass are both: guest). You can PM me to get write access if you are serious about it.
