Hi there, you can trade with any site that is willing to trade, you are not limited to TE3 sites at all. I usually suggest to look for sites with similar content (e.g. tgp ,tube, mpg...). Visit some of the larger sites, check their toplists to see who they're trading with and you can add these trades as well. This is a simple way to find trades. The advantage is that if you look at the toplist of your top 5 most successful trades, there is a good chance, other trades on their toplists will work well for you too.
