Need help with an Instructable, or around the site? Try here. Membership of the group means that you are available to help other Instructablers to do their thing. If you are willing to offer general help, just join the group. If you have a particular area of interest or specialist knowledge, then please also add a post to this thread thread to describe what you're willing or able to do.
If you need help, and you know who to ask, PM the individual involved (especially if you're trying to keep a project under wraps until the big reveal). If you don't know who to ask, then start a thread with the word "Volunteers" in the title.
