Mutt questions.

Hi again, I am in the process of moving over to Mutt from KMail and have a number of questions that I haven't been able to get answered from the documentation: 1) How do I setup my .muttrc file for multiple accounts for the same user? I have two seperate pop3 accounts that I would like to use, as well as an IMAP account. Can I have seperate "real name" and "reply to" fields for each account? How do I do this? 2) How do I switch between ispell dictionaries in Mutt? 3) I can see that Mutt can use other mboxes as well. What is recomended for migrating from KMail to Mutt? should I just change the default box and use KMail's? What have others done? I may have more questions, but this should get me off and running. Cheers, Brian
