Here's a list of errors we've found in the Winter 2005 Quantum Gravity Seminar notes. If you discover any more errors, please let me know, and we'll eventually try to correct them, or at least add them to this list.
I also wanted to point out that there is still something suboptimal in the notes which probably deserves to be explained in the errata. The problem stems from that weird mixup you had about frames versus coframes. As a quick fix, I changed the names and nothing else. In particular, the frame is still called e and the coframe f, which is opposite conventional usage. But probably the most potentially confusing result of this mixup is that you initally defined FM to be what by all rights deserves to be called the coframe bundle. This is why we ended up with a left G-action on our principal bundles and later had to switch them to right G-actions - because GL(n) acts most naturally on coframes on the left.
