email all users

[whybelieve]

I'm sure this must have already been covered but I have looked and looked and can't find it.

I have removed the registration option for people to select "don't receive emails from admin". but now they are all being set up by default as "don't let admin send me emails!"

So I either need to know where and how to make the default "yes receive emails" or have a mod. that enables me to send them anyway !!

Thanks for your help
