We are looking for someone very familiar with Aweber to help us combine multiple lists into one list without the subscriber having to opt in.
According AWeber, this is done by:
1) create a private app in their "lab" (the link they sent us)
2) add the coding they provided us to this app
3) install that in our account
4) that should move the list over.
Please let us know if you can help and have done this before.
