When I sent him the first two emails I believe he responded within the hour to both. This time though, that's not the case.
There is nothing I have ever read in the TOU that would prevent you from posting an e-mail.
If you do though, don't expect any further correspondence from him.
I think that may already be the case (still no response from today's email asking permission). And now, somehow I don't feel quite right about posting the emails even though there was nothing awful in either of them.
