Trip to the Dordogne area of France

My wife and I would like to visit the Dordogne some time during May/June 2013.  We like to have company and ideally would like to join a Rally. If anyone knows of a Rally during that time, we are flexible with the dates and lenght of time, could you pleas let us know. Alternatively if someone or group of people are thinking of going there and would not mind us joining them, also please get in touch.    Thanks in advance for your help, hope to hear something soon.
