Next month, iStockphoto's community of seven million members around the world are being urged to help bring awareness to men's health concerns and prostate cancer by joining the company in support of Movember .

Movember is a global initiative that includes a moustache growing charity event held during November each year to raise funds and awareness for prostate cancer.? You can participate in Movember in many ways and win fun contests and free stuff while doing something good. iStock will also match up to $10,000 of the funds raised.

To get involved, visit www.Movember.com, register for your country and join Team iStache. Then watch your moustache grow and raise local funds through friends and family to support awareness of men's health issues.

Men register with a clean-shaven face. The Movember participants, known as Mo Bros, then spend the rest of the month growing and grooming their Mos, raising money along the way. Women can still become Mo Sisters and raise funds too.

A Mo is defined according to the Movember rules:

  • There is to be no joining of the Mo to side burns – That's a beard.
  • There is to be no joining of the handlebars – That's a goatee.
  • A small complimentary growth under the bottom lip is allowed (aka a tickler).

iStock artists are encouraged to create and submit new photos, illustrations, videos and even audio compositions that celebrate facial hair or reflect men's health issues and general male well-being. Prizes will be awarded for files of each type at the end of the month.?Guidelines for having your work included in the iStock Movember 2011 collection are here
