Expected behavior When logging into the mdb site, and the login has been submitted show an overlay over the entire login that indicates to the user they are logging in, maybe the loading circle thing would be of good use here.

Actual behavior The same black text above the log form is show and you will probably notice that users are continually pressing login not knowing that the login is being processed. At least disable the form so that you dont have to process each of these submission as the user still things they are not signing in. This could reduce load on the server if the requests are being processed and a better user experience. Resources (screenshots, code snippets etc.)
