Description

There are multiple accessibility bugs. First, all the mouse over menus. They should be properly made accessible to screen readers using aria, or at least have a setting to turn them off. I can't figure out how to access most pages in GOGS because the screen reader doesn't know that there is a menu there because screen readers don't use mouse cursor to pass over items.

Second, the captcha service you use is not accessible (why not use recaptcha or have a new to define your own captcha via php so I can add a question captcha(?
