Their is a bot called orange bot I am told it works for the private server as well but in my reaserch,in the posts there seems to be a bit of a problem with said orange bot. There for I have not downloaded or atempted to try. Not to say it does not work and was not installed properly by said persons complaning it dident work for them.On that note good luck and a simple google search for FW Orange bot should take you right to it. I will leave it to your discresion to use it or not.
Best of luck Doc
