I have noticed that http://visualhud.pk69.com/ no longer works. Some time ago I tried to contact the original developer but saw no response. Today I have deployed VisualHUD on Holysh1t.net. Basic functionality works, but I have disabled the counter of the total huds made and removed code involving a backend database. If you want to be able to edit your HUD later, make sure you keep the .vhud file included in the .ZIP file when you download your HUD.
This version is the one that is found on the official VisualHUD Github page, it lacks the widescreen changes introduced some years ago. If you wish to make your HUD widescreen capable, read this article.
