it probably was wgat started this conversation, I didn't know there was a challenge topic and saw so many transformers that I wondered what was going on. I thought everyone went transformer crazy, but ever slow, I now get the picture; and speaking of pictures, an 'interior' challenge (with nice lighting )would be an event not to be missed...

anyway mike, thanks, I think I finally got to the bottom of the mystery (re, thread) , the challenge topic, I've had my head stuck in a 'sammy the seal' tut and hadn't tuned in here lately. Anyway I'm paying for that course tomorrow and then in 6 months I might be confident enough to even enter a challenge but right now just watching is fun...
