The google docs talk on creating classlists is very good. We should consider promoting the link to it to the top of the page.
I'd like to see a similar doc that goes through the format required for the classroster.lst documents which are uploaded. I get a number of questions on that. In particular folks create classlists with passwords but forget to encrypt the passwords in the .lst file. The other thing to mention is where the description of the required format can be found (on the wiki) or in the help ballon on the File Manager page. --Mike
