A pleasure...

Actually it is a conceptual question. There is no right answer, because both 
approaches has advantages and drawbacks. 

I played around with Kontact's calendar and it seems to me that the 
appointments use the time range as basic reference, while in Lotus I assume it 
is the name. 

For example: Dancing lesson - 17:00-18:30 - every Monday.

In Kontact you can change everything and the reoccuring appointments remain 
together (as repeating occurrence), EXCEPT the time 17:00-18:30. As long the 
time 17:00-18:30 there is no problem. Change the time (except having 
exception, which we can set) and the "chain of appointments" break as 
discussed above. This solution is logical, easy to grasp, but cumbersome in 
some cases.

Now in Lotus they may have set the name of the appointment as a common value. 
We can change everything in any of the reoccuring appointments, BUT the name. 
So as long we the name Dancig lesson it remains  chained together. This is 
logical and flexible, but very difficult to visualise in an easy to use way.  
Imagine having  Dancing lesson as a repeating event for 3 years while the 
regular time changed three times, had 7 exceptions, etc. How do you handle 
them? Have them listed under the appointment if it opens up? Where and how to 
indicate that that (or the other) appointments are exceptions?

Coming back to the question, yes I can imagine a situation where the "Lotus-
like" version is convenient. Actually I just have such a case... But on the 
long run it will become too detailed and difficult to overview.

Again, my main problem is how to  presentation the information in acceptable 
way. Any ideas?
