Hmmm ... I don't really understand why there are groups ?
I'd like to be able to set groups that can trade with each other.
For example, on my tube site, I got 2 types of trades : the ones with small movies and the other one with big movies.
I don't want to mix the traffic and it looks like TP is not able to handle that case then ? :/
And changing the forbidden domains is not an option with 40+ trades ...
