I'm in a hurry so this is an answer to several posts. I do zap. I made my own. If I could afford it I would buy one of the zappers that automatically times everything. That is the one thing that is hard to do and once when I forgot to do the second zapping I got a cold.
I no longer try to name the worms. Worms is worms as far as I'm concerned. Once I have a synchronizer I'll be able to accuratly name them till then I'm not worried about it.
