Ok thanks for the reply, I looked at all them nice features and add-ons but maybe something more specific. Can I disable anon registration and whenever someone tries to register I can either say yes or no? Sorry if it is at the mod site I just did not see something like that.
Yes, you can approve member registration and even have the members validate their email addresses. The options for that are available at Admin Options -> Email Server Configuration. To have members approved before being allowed to login for the first time, set Restrict Registration to On. To have email validation, set the option with that name to On.
