As both an agency and a volunteer, Volunteer Base is easy to use for both sides. Posting as a host is simple, and allows you to offer accommodations to your volunteers (such as sleeping arrangements or refreshments on site). As a volunteer, it is simple to search for volunteer opportunities that fit your interests. Easy to create an account, and to update your details as necessary. You have a minimum word limit on your description, which makes it less likely that someone does not give enough information about a project.
