How it would work:
Say you know you'd be inactive for a few days. In the settings option, you could change planet production to the base.
This would remove ALL of your own production. You'd receive nothing. Also, you'd be exempt from base resource divisions (more for others)
By channelling production, your own planetary production is added to base production, and distributed amongst active members.

This would solve the problem of going away with a "full ship", a prime raid target, and would put wasted production to good use.

sounds like it could be abused too easily with multis...

true... how about a time limit and cooldown on the effect? say 2 weeks, with 2 week cooldown?
And a nerfed production bonus for the first few days (say 20, 40, 60, 80, then 100%)

-1. I see this as a powerful ability that can be abused. There should be a limit to how many planets can be used with a base.
