Mulberry

Mulberry is the most well-behaved of the applications I have been able to use. It does have some bugs, however, and a particular annoyance around it's use of non-standard names for time zones. Mulberry is the only client I have used so far which can issue a MKCALENDAR command or which will display a hierarchy of calendars from a single configured URL, dicovering the calendars through recursive PROPFIND requests.

1. Select "Preferences" from the "File" menu.
2. Choose the "Accounts" tab
3. Select "New" from the "Account" drop-down and a "Create New Account" dialog will appear.
4. Enter a name for the account, choose "CalDAV Calendar" for the type and click "OK"
5. In the "Server" field enter the domain name of your CalDAV server, such as "calendar.example.net"
6. In the "Authentication" pane of the "Accounts" tab, enter your username.
    
7. In the "Options" pane of the "Accounts" tab, enter the path, which should be "/caldav.php/"
    
8. "OK" the preferences dialog
9. A list of the users and resources which you are allowed to access should appear. Some may contain calendars.
10. If you don't already have a calendar for your own user, ensure your username is highlighted and choose "Create" from the "Calendar" menu.
11. Once you have a calendar created, you need to subscribe to it. One way is to right-click on it and choose 'Subscribe'.

Caveats

Unfortunately Mulberry is not (yet) open-source, though it is free, so we must wait on the developer to fix the user interface niggles when he gets around to it.

Note that Mulberry has a complex user interface. When I wrote this I went back into Mulberry and initially thought that RSCDS had regressed somewhat and that these instructions didn't exactly work... :-) It turned out that these instructions worked just fine when I followed them to the letter the next day. Go figure. I think I need to record some screenshots of this one...
