Regarding mentoring, I noticed you said tapes, are there more than one??
When submitting a tape in (after having contacted me for more details), of the signer which is about 5 minutes long of signing, I return the tape back to the signer. I also include a second tape that has my taped feedbacks on a seperate tape. This enables you to be able to redo your original story/script on the original tape after your story and save it to refer to later.
