What if there was an in game message board of some type or form that allows players to leave messages/missions/etc. For other players?
It will spawn as an entity or prop or something near/inside the spawn area, And when players walk up to it and "use" it, a small menu interface will pop up on your screen the same way the community/inventory/etc menus do.
Players can write messages on this board, with topics like:
in-game RP notices: such as locations of bases, radio frequencies, and etc.
RP missions/ requests from other players, Such as offering a reward to any player who destroys an irksome Antlion mound.
Recruitment flyers for Players' Various communities
Anything goes so long as it fits RP.
On another hand, Maybe make it so each individual Community can spawn their own message board interface, it can be posted on by level 2 & 3 community members only, but any player in the game (regardless of community) can read it.
I just figured something like this wouldnt be too complicated as far as coding goes, (idk i may be wrong lol)
and that it would help to increase RP on a whole.
