Just wanted to separate the below post a bit and I pulled this bot script out to do so. It simply grabs the RSS feed from the given list of URLs and posts any changes to a given channel.

	readdata = ""
	urlnlist = ["www.reddit.com/.rss", "rss.slashdot.org/Slashdot/slashdot"]
	resllist = []
	
	xmlshead = ""
	xmlslink = ""
	
	for urlnitem in urlnlist:
		uobjdata = urllib.urlopen("http://" + urlnitem)
		readdata += uobjdata.read()
	
	readdata = readdata.replace("\r", "")
	readdata = readdata.replace("\n", "")
	readdata = readdata.replace("<", "\n<")
	
	datalist = readdata.split("\n")
	
	for dataitem in datalist:
		regxobjc = re.match("<title>(.*)", dataitem)
		
		if (regxobjc):
			xmlshead = ("[" + regxobjc.group(1) + "]")

			xmlshead = ""

	if (len(resllist) == 0):
