Trying to find an addon (or something similar) I encountered years ago.

So I haven’t been much up-to-date with gmod in quite a while, and now I got stuck trying to find a very useful addon which basically let the players on a server ‘subscribe’ to the server-side errors. The client ran a command and specified where they wanted it displayed, after which any server-side errors that occurred would be sent and displayed to the client. This was very useful when playing around with Luapad on a server where the majority of the Luapad users did not have access to the server.

The closest I have found so far is ‘errorfinder’ (http://forum.facepunch.com/showthread.php?t=864376), which seems similar although more clunky. Also the date ‘2009’ makes me doubt it still works (cough gmod13 cough). Anyone knows of the one I am looking for, or at least other alternatives for me to look at?

As a side-note, Luapad is not exactly maintained. I did find a gmod13 fix on the workshop, but while searching I also found an alternative (http://forum.facepunch.com/showthread.php?t=1245803).
Before I decide to switch to it though, I figured I could just as well ask if people know something in regards to similar addons I should look at as well?
