hmm, i tried adding you to my watched users list and it took it.
the easiest way to add a user to your watched user list is to do it from either a persons profile [there is a link there] or from any post they have made. just click on their name and a drop down menu appears inviting you to select the option to add them.
if you want to watch a topic [have it sent to your email], you can select that option from within the thread itself, up in the left hand corner of the page next to the 'new reply' tab, where it says 'topic options'.
see if any of those options work out for you....
