So in ARK: Survival evolved they added a Admin log to tribes, It exists as a flat text file on the server itself
This is what it looks like:
http://puu.sh/ltaUB/f219a51027.png its on the left, its not much but its a basic log
it limited to 100 entires(by default, modifiable on private servers) of anything that is an admin message.
Players killing tribe owned pets appears in the log.
When a player demolishes a structure its in that log.
I believe when a player changes another members level its also documented "playerA changed playerB level to Admin" but that might be another game im thinking off.
When the log wraps the oldest entry is truncated.
It doesn't have to be a log on a chat console, if there was a button to bring up a UI similar to what you have on the quest window, where i can click on the event, then click a details button and then view the information spefic to it, then i should be able to close or delete the entry.
you can list the player, summary event and time/date
with the following types of events:
-When a member of a tribe joins.
-When a members rank is changed, along with who changed them.
-When a member leaves the tribe.
-When a structure is demolished.
-When a construction ghost is canceled.
in fact this is something that could be monetized if added: a small 10-100 basic log of events with a larger one for totems with premium time. Perhaps even adding the ability to lock 1-10 logs if players have totem time.
