a2sd + titanium backup?

[wooten409]

Ive searched found threads on a2sd but none that specifically answered the question below....

Running android 2.2. on fresh rom.

If i want to move apps to the sd, AT THIS TIME, is it mandatory that i partition it?

Im asking b/c in "titanium backup" theres an option to "move user apps to sd card".

Can i use that option w/o partitioning the sd?
And are they're certain apps i shouldnt move?

Thanks!
