Heres what I got: (if some exist, can you link me a download please?)
1) Displaying the player's affiliation as a prefix for the name in the chat list.
2) The player gets an affiliation only when the reputation is 10
3) (Alternative to 2) The player can have a maximal reputation of 8 with a faction.
(About 2 and 3: whatever is easier, but IMO #2 would be better)
If something of those is a default INI entry of FLhook, then consider it as my fail.
