For the sake of consolidation... Here's a nice place to post Trail Work and Area Clean-up Volunteer opportunities.
If you're interested in me posting a volunteer opportunity in your area on other forums, please feel free to send me details (where, what, who to contact). firstname.lastname@example.org
Also, a reminder that if you are a partner/member club or a 3-year individual member, you qualify to apply for our stewardship grants to help fund these projects. Stay tuned to the Stewardship Grants thread, or have a peek at the website: Tread Lightly - Stewardship Grants
Thanks. And feel free to post up your own stewardship projects here as well
