My suggestion is the following:
There should be some board, or notes which are automatically delivered to newly entered inductees. Why? Sometimes, there are some unwritten agreements between cabals, for example, once I was in nexus there was an order from an elder, "Do not break laws, we are working toward an alliance with the Tribunes". Sometimes, such agreements stand for a long time and when new inductees join the cabal, they are not aware of them. It will help for the better organisation of a cabal.
On this board, the highest ranked person in the cabal can write. Something like the bounty/captures boards syndi/trib have.
Small suggestion but I would find it somewhat useful.
