Isn't the salary already on the tooltip?
Also, a weekly message would get really old really quickly.
Oh, missed that bit in the tooltip. Derp. Yeah, maybe no weekly message. If you have no relay sniffers you only get 2-3 messages a week, and a weekly report might bother you. But if you have many relays tapped, you get a douzen a week, so 1 more isn't a big deal. But better play it safe. Anyways...
Crew now require salary payments; if you run out of money, they start to mutiny
Related economy issue: I've noticed at the game's start the price of supply is consistently 200+ credits in all systems, but the overproduction in Anar can depresses it as low as ~60 credits (I think in vanilla games it never drops below ~90, even with favourable coniditions and high stability on producing planets). I've brought it up with the mod (Shadowyards) creator, but (s)he doesn't seem to care much as they'd rather attract more players to their home system.
However, I'm guessing you want to increase ship upkeep costs overall, given your doubling of fuel consumption and addition of crew pay. If this is the case and you're actually trying to increase upkeep, the Anar supply overproduction may be ruining your attempts by making supplies much cheaper than normal.
Maybe throw together a mini-patch that overwrites the production values of Anar, or alternatively, maybe increase supply consumption of one of your mods' worlds (Thrace's interstellar bazaar perhaps?). Although the latter method will be much harder to balance if you want to avoid chronic supply shortages that players can exploit for profit.
