FTP is probably the worst choice in multiuser environment. In general that is the last option to use if you cannot get anything else to work. My suggestion is to use the WebDAV (or well it's basically just http in Rainlendar) protocol instead.
So changing ftp://domain.com to domain.com
solves it or what? For http I could add a new folder and inside the new folder I add a .htaccess with login protection. Is that the thing you need?
You need to put the private events into a separate calendar (I.e. create a new calendar in Rainlendar's options and add the private events to there instead of the shared calendar).
ok, I found this explanation in the help file: "The event can be marked also as private. This doesn't have any functionality in Rainlendar at the moment but it might be useful if you export the events to some other calendar."
I don't know what you mean by this.
If you add a new event the calendar "Default" is selected first. But if I want an other as THE default one I can't find the option to do that.
