How Do I Submit a Resource?
Once you click that button, you'll see an overlay that allows you to select your resource category. Try to select the most appropriate one.
Once you've done this, you'll be redirected to a page that allows you to enter the resource information. This includes the title, a brief tag/summary, resource type (ignore the upload - select no file), resource description, alternative/support link, and tags.
Try to be as specific and descriptive as possible. For the description, make it original and factual. After this, click save at the bottom. You've just submitted a writing resource.
