Had to create new user to fix mobileme sync issue, can I use time machine?

Question

I had to create a new user for myself. I want to associate the new username with time machine backups
that I currently have, and not start from scratch of course.
1. Will using time machine at this point:
1.1 create new backups?
1.2 delete whats on the disk and then create new backups?
Last time something like this happened (I dont remember the details) I lost all my backups.
At this point I d like to be able to use the current backups with my new username and not lose any data/backups.
Thanks,
Eric

Of the new user account, yes.

No. Time Machine will never delete anything from your system. But it will, eventually, delete it's copies of things that no longer exist on your system.

That's going to be difficult, since OSX in general (and Time Machine in particular) think those two accounts are for two different people, and neither should have much access to the others' files.
Why did you have to create a new account?
Is the old account still on your Mac?
Assuming the old account is still there, your best bet may be to sign on as the old account and grant permission to your files to the new account; then sign on as the new account and copy them. But until you're sure you don't need anything from the backups, don't delete the old account, so you can use it to restore anything you need.
