PIP claim and evidence

Cruella wrote: Hi, more advice please.
1) Is it ok to use doctors' letters that have been emailed to me as evidence, once printed off seem just like a copy of an original letter.
2)The doctor has my christian name, surname , date of birth and address correct on the letter but there is a mistake in that my title is Miss and the letter refers to me as Mrs throughout, do you think that ok

2) I have 2 letters from different health professionals saying why I would not be able to attend a medical assessment centre . One of these letters doubles up as evidence for diagnosis so will they use that letter for both, should I send 2 copies so that i can be used both to explain why I cannot get to an assessment centre AND be used as evidence confirming diagnosis?
