Replying to my own post....
Never mind! After looking closer at the problem - I am really at a loss as to why the newbb module uses cookies at all - they are problematical, aren't stored under a user name (two people on the same machine/profile share read flags!) and of course are completely dependent on people allowing them in the first place. The data stored is minimal (at least on my site) - a few hundred characters per cookie. Can't this data be moved wholesale into a new column in the user table, or a new table added for newbb referencing the user table?
Thanks,
Marc
