ULX ExLua - Run lua code on your server.

[LuaTenshi]

Have you ever played on servers like GCinema and saw them execute lua code with their fancy name syntax?
Well now you can do that too with full error reporting, and even working ULX keywords such as ^ to target your self.

Code: Lua

If you find a glitch, or an exploit please email me or PM me. For other inquiries and or comments please post below. Also if you like my script feel free to let me know.
The forums add [url] tags to the link in the comment of my code, those make the MD5 no longer match, so before verifying make sure to remove those tags.

Wouldn't this be better in RCON rather than Extra Utility?

Probably would, I just like to keep the stuff I make under one category, feel free to change it.
