Lyndel and I have spent a lot of time on the 7000. I'd be quite close to 100 hours as well, and that is not counting the time I spent migrating and the redesigning my CCF to the 7000.
Lyndel was really strong on the User Interface of PPENG and migration issues. I concentrated on previously reported bugs, upload/download/learning, stress testing.
Together we exchanged very many emails tracking down bugs before and after we posted them. Lyndel showed amazing patience in his detective work.
Together we've been working on new utilities for the PCF format. Lyndel is doing SNL, and I'm doing PCF Explorer (which is almost ready for release).
