How do I trade?

[KarmanMonkey]

I'm obviously missing something; how do I trade tech with another player? I can't seem to see the option, and I'm missing out because I'm playing the race that's all about trading.

You can only trade with player whom you are in contact and at peace with. So that is the first condition you must fulfil. If you do, then in the Trading Phase colored windows will pop up allowing you to select technologies of other players to trade with. Click on the icons of the technologies you want to gain.

So if they have ships at my planet and we're at peace, the option should pop up? In that case it must be a bug.
