Download the Plugin and the Filterscript, make a new folder at the place where Samp-Server and name it "Plugins" and put the plugin in it, open server.cfg and edit the "plugins" line to "plugins irc.dll and edit "filterscript" line to "filterscript irc", then open the "filterscripts" and paste the "irc.PWN" and compile it to irc.AMX and then run samp-server, simple, i hope this helped.
