Much like the seasons, Napoleonic Wars in terms of population density and distribution changes; from the spring-like growth to the niche to summer-like comfortable confinements of regiments. Bad analogies aside; there is a stabilizing effect on the public player population and large chunks are now part of regiments and confined to trainings, regiments events and such. Now, only some North American community organizers seem to accept public players into their events. Sadly, the current state on public enlistment in European events are unclear at this time.

An example of one of the linebattle events:

I strongly suggest that anyone interested to join in on the community events should start by joining in the public regiments before joining an actual regiment.
