mmm... good point
I suppose that doesnt make much sense, unless you're me.
Can anyone recommend any email address verification scripts/modules. I
verify to check email addresses for 'validness'. Also I heard about
Mail:CheckUser. Has anyone used this, or have any opinions as to wether it
is half-decent or  not?
