S-T-G,
There is a CTC Cadets forum, but I suspect the guys get extremely busy once out there. We'll try and keep the forum updated, though.
In the meantime, you might like to check out the website set up by previous groups of cadets such as ctc19.com (CP19) or cadetpilot.com (CP29/30). They've got some great photos on there.
If you need any advice for phase 3, i'd be happy to help - having done it twice!!
JP.
