I just launched my Creighton family site recently, with my current Creighton family research. I'm constantly adding new information to my files, and will be attempting to update the site about once a week.
I'm quite interested in connecting with other people who are working on this Creighton tree, especially for extending it into Ireland - and to the supposed origins in Scotland.
Sign up for an account to get the most out of it. Living people (as far as I know) are hidden from public view and also have all facts removed.
I can set you up with edit privileges if you want to add and edit information to my particular Creighton tree. Or, as I can add multiple GEDCOM files to the site, I can set you up to administrate your own GEDCOM tree (If it relates to one of the primary families of my focus).
