huggybear - I agree I am here the website is a little misleading on the accommodation side of things.
With regards to the 200 hours multi instruction time yes a multi engine instructor rating would be required. NONE of the hours are guaranteed - neither is the place as an instructor - you could accumilate up to the given hours if you instructed for that long.
With regards to Trevor's email - there are a lot of APP students here currently and it would not surprise me if they are almost full for the year - I think you are reading far too much into the email.
