Increasing the Garrison resource cache limit to 1000.

Let's face it; I have too many toons - 14 - and too many Garrisons - 9. I don't have time to visit them as often as I would like.  Since a Garrison makes 6 resources an hour, it makes 500 in 83.3 hours or 3.5 days.  You have to empty the cache twice a week or it overflows.  You can raise the limit to 1000 by buying a "contract" from an Arakkoa vendor in Tanaan.  This takes 3 things.

1. You have to become Revered with the Arakkoa.  Go back and do those quests you left undone.  You get 275 rep per quest if you have reached Honored.  Revered takes 12000 Honored.  So, for each 1000 you have to go you need 4 quests.  The last  toon I did was 5700 Honored when I started.  I am not yet done with the 23 quests.
2. You have to get to Tanaan.  This means doing the invasion which starts with a nasty quest to get the shipyard Architect and Plans from Iron Docks (I relearned what the little red man with the little red sword next to him meant). Buff your armor as hard as you can and bring a friend.  Then you have to follow the quest chain until you build Lion's Watch.
3. Buy the "Trade Agreement: Arakkoa Outcasts" fromVindicator Krethos in the Lion's Den in Lion's Watch, Tanaan.  It cost me 2375 Au.  Right click on it in your Inventory to activate it and Bob's your uncle.

One small detail, If you look at your cache, it will say "Full" after it reaches 500, but it will continue to fill until 1000.  This may get fixed sometime.
