Looks like AddQuickTag only works for admin users on my blog. I'd like it to work for contributors, authors, and editors as well. The HTML quick tags are there for contributors, authors, and editors. But, nothing shows for them in the Visual Editor.
What pieces of the code would I have to change to enable this feature for other user roles? Please leave your PayPal address in the message, I will donate to anyone who can help me solve the problem.
