@Otterkins: same for me. I gave it a try and dropped it for 6 months. Then I tried again and began to make sense out of it. IMO PS is worth the effort, but only if you really intend to keep using it. It's not a one-time application...
@Blowhard: I fell like crying a four-letter word that begins with F and ends with K out loud when I see you engines and guns... (I case you were wondering, the word in question is "fork". I hope no evil mind had been thinking of anything else...

It's a fantastic job. What you mean by "lots left to do" beats me, but I suspect you're just trying to frustrate us! lol
