"I am pretty much in total agreement with Evil Rich. No direct tech trading, but ship trading to get tech the hard way is fine. Any other gifts trades are fine with me as well.
But of course if the decision is no ship trading I will comply.
We need clarification though if we disallow ship trading for the puposes of accquiring tech, do we still allow it for the purposes of population swap? Do we allow pop swap at all, or make people get the pop the hard way as well?

I'm with you. As far as I am concerned no direct tech trading (I will turn both of the 'allowed' options to off) but if you want to trade ships so be it...just good luck gettin them back to your shipyards in one piece

As far as pop swap this I leave up to roleplaying, if your Emperor would trade masses of his population like herds of cattle then it's ok. I just can't see some benificial ruler doing it. Immigration and emmigration sure, it happens in real life. (but again, those pop liners are sure targets for capture or blowin'up.)
The only request I have (and this is a personal one) is no Colony Ship trading (I guess capture is fine). All empires having all three colony tech's by turn 15 is just cheeze IMO.
