Newbie question... Is there documentation anywhere?

[bonsaipark]

I've been switched to Roundcube Webmail 1.1.2 by my ISP.  As a 20-year computer and Web user, I hate to admit this, but I can't make any sense of the setup or properties. Is there any user documentation anywhere?

Special Folders is particularly baffling (for example)...

  Show real names?

  What's the purpose of the list of folders where you can pick "Sent Items" or "Spam" from a drop list next to "Drafts"?

  What's the difference between "Junk" and "Trash"?  Between "Sent" and "Sent Items"?

  Where IS the "Archive" folder???

This is totally incomprehensible.

Here is the end user documentation: http://docs.roundcube.net/doc/help/1.1/en_US/

Thank you.  My support person will probably appreciate this link, as well.
