I'm trying to turn some 500 Thunderbird email messages into PDFs. I guess I would have to do so, with a total of around 500 pages of document, if I were to pick all these messages and convert them to PDF on an individual basis. (which I didn't try.) So when I select 'Print' and then select 'Download PDF,' the previous message will be replaced by each message. Does that make sense logically? I want to convert 500 messages from my Thunderbird account to a new PDF format.
