Customizing Ajax Customer Notications

I am just in the process of having someone design my site and I wanted to find out if moving or changing the size of the ajax customer notifications requires knowledge of ajax - can this be rearranged on the page easily?

Sorry if this is a simple question, I just need to find out in case as my designer is unsure of ajax.

btw the notification I’m specifically wanting to change is the one that appears after the customer registers an account - I find the way it currently works is confusing and can be easily missed by a customer.


It does seem to me like all notices pop up in the top right corner which can be missed.
