Sure this must be somewhere around but can't find it yet...

can anyone please point me to the code that I would need to add to force new users to fill in certain fields in the
register form??

This time specifically, I would like their name and location to be filled in.


To extend this, to ensure that the input information is valid for that field...for example, location might be from a set of known values if the userbase was a limited one....


thanks.
