Thanks for that. I did try that out and it still says I'm blacklisted. I also tried a non-incognito window with extensions off and it still says I'm blacklisted.
Maybe I made the Simple Machines devs mad or something and it's hard-coded to keep me away!
The forum and the wiki are separate entities. So anything you did here will not affect you there. Unless someone who watched you here would have reported you there, but I doubt that.
I have not heard back from the wiki admins...
I did some testing creating an account there. It may be that multiple digits in the name are triggering the ban.
Maybe try something like willbprog9EE
