We use the newletter plugin an a different way from most. We do allow people who visit our website to get the popop and subscribe. However, as a company that runs a sailing school, we also want to send newsletters to our customers, the people in our database.
I have a PHP program that lets us upload our customer database to the newsletter database, and assign these people to a specific list. And my program “knows” what that list number is, and also knows the list with subscribers (the list that new subscribers get assigned to automatically).
What I would like to be able to do is flag a list as ‘locked’ so it can’t be renamed or deleted or have anything done with it. In my case, for example, I would lock the 1st three lists. This way, no-one could mess up the lists by accident. They would first have to unlock it, and then mess it up!
The people using the newsletter plugin know what they should and should not do, but people make mistakes.
If anyone knows how to do this (I am a programmer, so I can actually go in to the plugin and make changes), please let me know. If not, perhaps this could be a request for a feature. Others might find this useful as well, to prevent accidental messing up of lists.
