I'm not in Command Staff or the Mod Team, and PFC Brewer already covered it, but I just want to underline it for anyone else who reads this post:
Only run the mods listed in the 506th MOD UPDATES thread. ArmA works in mysterious ways, and while a mod may be client-side, that is not a guarantee that the mod won't negatively affect server performance or have serious conflicts with other mods. During the FTX last weekend there were 12 people running JSRS Dragonfyre on one of the servers, and while it may not have fucked anything up a week ago, it could in the future.
The only client-side mods I would even consider running are, as PFC Brewer said, the STHUD and Stamina Bar. Most members of the unit use and have used these for a long time, and, as far as I know, there has not been any issues or conflicts related to them.
I've played ArmA long enough to know that one mod or small .pbo can cause a lot of issues, so please just stick to what is unit-wide approved.
