it isn't important the most important thing is that partner must SPEAK or at least send some messages to you couse alot of them are forgoting you and even don't chat with you. It is bigest problem of this web-site . Man or wooman it isn't important for language exchange!

your partners gender can not be acounted as a criterria..good partner is whoever that makes you to improve your skills . he/she may use different ways to make you to do this.i prefer to have a native speakers as a partner.

You look someone in the professional language environment more, such as who has the most of interpreters, who are more diligent and patient and understand everything.

A friendly intelligent person with good sense of humor. I don't care about my language partner's gender. 

It's really all personal preference. Daisy wants a woman and mojtaba wants a man. Personally, I don't care at all and I think that a teacher's efficiency should be based on that teacher's abilities and not his/her gender. I don't think this is a dating site at all since the people I talk to are on the other side of the world and anybody that uses this as a dating site should really get out of the house once in a while.
