I cannot give you the code, it is a big custom plugin the owner specifically built for his servers and is not updated to work with CS:GO which is why I need an alternative. The base plugin is a single .smx file which is used with SM across all our various source games and it does not function with CS:GO (popups) just our backend ban system.
Unfortunately he does not have time right now to update this and I do not have the source code which he would not want given out either as it handles a lot of things from our backend ban system, map configurations, admin system, forum linking etc.
Edit: If nothing exists then I will have to get it custom coded.
