This should be an easy one.

How can I contact a model member who lives in my hometown thru MM?

Use browse to locate member and MM # > find the envelop symbol on their page (upper right under their MM #) and click on it to send a message. 

Here is a Browse result within 10 miles, including males & females, since you didn't specify.  https://www.modelmayhem.com/browse/resu … _counter=7
