It seems that 24 hours is not long enough for some people to verify their email address when registering. Yes, I think it is, and yes we have put clear messages on the page - but people obviously don't read those messages.... and we are having some new registrations wiped out by this 24 hour period expiring.

Anyhow, regardless of peoples silliness at not reading ---- how do I change it so that, for example, we give people 48 or 72 hours to verify a new registration mail rather than just 24.

Thanks.
