I've put a new bot online, which will send alerts when new torrents for your favourite TV shows are released. If you're on the Jabber network, you can connect to it by adding 'torrentbot@hubmed.org' to your buddy list.
Send 'help' to show the commands, 'list' for a list of all available shows ('alpha' to list them alphabetically), and 'subscribe showname' to receive alerts for a particular show.
There are plenty of good Jabber clients now, if you need one: Adium, Psi, Fire, Exodus, Miranda, Trillian to name just a few. Most of these work for other networks as well, though the specialised Jabber clients tend to have more features.
