address list?

I would like to use kplato. I downloaded it and tried setting up a 
project, but quickly ran into a problem where I was unable to 'select 
addressee' when creating a task.

I get the impression that kplato is looking for some kde address book - 
is this the case? I use thunderbird. Can I do anything to get past this?

I entered two tasks and I can't see how to link the second to the first 
as a dependency or task to be completed first. I guess I could do with 
some more help in that area. Is there any more documentation other than 
the Help?


Thanks
Adam
