There are a few ways of finding information on Crabgrass:

This is a very basic introduction. It doesn't, for example, tell you how to edit pages or add to discussions. We're hoping to make some videos of how to use Crabgrass soon. Watch this space. In the meantime, we encourage you to have a go - you won't break anything, and if you make mistakes you can always re-edit pages or revert to previous versions of the page. If you get really stuck, get in touch with us.
