Mia - I don't think you are following a pipe dream! I think you are being cautious which is fine! I personally haven't heard those questions on the exclusions but someone else might remember from the phone calls.
Also, I wouldn't feel bad about bugging them either. Babybearjmd (Janice) bugged them for several days before she heard from someone! They may have missed a number on the voicemail and can't reach you. You never know. Try both phone numbers on the website too (don't call Maryanne directly because she's swamped and told me she rarely checks her messages). I think the secretaries are doing all the screenings first and then passing them on to Maryanne. Good luck, hon! I hope you get in! I'll be saying some prayers for you!
