-- Easy Config:
local reports_enabled	= "1"			-- Set this to 0 if you want to disable this script
local reports_in_logs	= "1"			-- Set this to 0 if you don't want to log reports in daily logs
local reports_interval	= "120"			-- The player can only report once then he need to wait this interval (seconds) before reporting again. 0 = no delay (not recommended)
local reports_folder	= "ulx_logs"	-- By default, in the same folder as others log files
-- End of config
