I have 2 separate opt-in forms on my site; each for a different list.
If someone puts in their email on one opt-in form and subscribes to one list, will they be able to enter their email on the second opt-in form for another list?
Yes, that's possible.
jvstratum how so?
I have two lists and it says duplicate email when I try.
The two separate links are at the bottom of www.backyardwx.com
(Example daily list)
Can you check which lists you have enabled in your subsciption modules? It looks like you have the same list enabled in both modules. Otherwise double ckeck that the user you are testing with was not already subscribed to the list.
