PHP Code:
#include <amxmodx>
public plugin_init()
{
register_clcmd("say help", "CommandHelp")
register_clcmd("say ajuda", "CommandHelp")
}
public CommandHelp(id)
{
show_motd(id,"help_motd.txt", "Help menu")
}
create help_motd.txt in cstrike folder.
Hope that help's you. (This is the easyest way.I think...)
