Hello, here are my two questions:

1- First, what kind of different storages the Caldav RFC accepts? I was not able to retrieve this information, because lot of people seem confused between these four words: notes, memos, tasks and todo.

2- Second, SyncEvolution support two different backends for the things I understand to be the same concept, and give this description in the documentation:
    So what is the difference between memo and todo? ownCloud and Thunderbird Lightning seem to call "task" the todo concept, and I've never seen a "memo" implemented.

Enlight me please!
