We should never use again our MAIN HORSE to host a events because not of all of our playerbase aren't in the moods, or doesn't know or would join to late because of reallife thingies.
We saw what happen lasttime. The player WHO DONT CARE about events joined another server.
Events should be hosted on any of the 2 testservers. All we need is more advertizing for such events .... also on PR forums. We are able to make really nice PR coop events with all Vodoo Magic, gadgets etc.
A locked server for such events are better because you can do more NICE stuff serverside what belongs to the corefiles (mostly ai things) and custom content that is designed for the events.
We could also create our own mappack copies for events what generally give us more freedom. All GPO's could get a setup with all the defaults lines to make later any serverside changes easy for other or future events.
We can also create stuff for our purposes only to make events more special. Creating a own event_core_server.zip.
When we really want, we can fill up our server with any event. We need only a good reputation for GOOD PR EVENTS or GOOD ARMA EVENTS.
I'm generally for more events at all. Who remember the time where we created special campaign medals and ribbons for ArmA2, PR and FH2? I liked that much.
