When attempting to add nicks to the notify list trillian crashes to the desktop. Simply typing /nadd nick is sufficient.
This occures under either Win2K Pro or WinXP Pro (RTM). I have the option "Use Masks on Notify" set in preferences.
Additionally, the help indicates that if using /nadd or /nrem are confusing, to use the GUI. But I can't find anything in the gui at all the relates to the notify list, unless adding "friends" automatically puts them in your notify list. It definately seems like something that should be in a dialog somewhere, so perhaps I'm missing something.
Feel free to e-mail me if you need any additional info.
