I start in Oct and have heard so many discussions regarding the importance in having interest in your PhD topic (see 26/08/05 PhD proposal entry).
Forgive me for sounding naive Bob, (dig at 28/08/05 entry PhD morons) but I am unsure of the precise area of my PhD. Dont get me wrong, I have a vague idea and have some interest but have not looked into it further (busy doing MSc dissertation.)
Cheers
