I usually check out other people's signatures on Yaxay, WHT, etc. If I remember correct, I saw Robson's signature on Yaxay that said TalkFreelance Contest or something.

It's always going to be better to have quality over quantity. In comparision to TF, I'd suggest staying away from places like Yaxay with many teens. Focus on more knowledgeble websites that will generate good discussions here at TalkFreelance.
