Hi,
For Readability, I would put the extended use case in a separate diagram and refer to the other diagram with a note. In Rose you can link the other diagram through the note. Communication is the key. If the sequence diagram gets too complex to communicate well than find a better way to communicate your ideas.
Also, avoid repeating the same sequence in every diagram.... for example the logon sequence which can be accomplished at different places in systems.

I saw a lot of messages here talking about seperate a big sequence diagram into 2 or more diagrams. And some guys talk about "Notes" to connect the diagrams together.
But, I wander how it can be. Say, I have a big sequence diagram. If I divid it into 2 diagram. There would be many "message" line between these 2 diagram. And, how can I put the information in those diagrams?
