Hello, I don't know if this is a bug or it is supposed to work so. If I go to Admin->Newsletters I have the option to include and exclude membergroups from a newsletter. If I click on "Check All" from the Exclude members I get directed to the membergroups from "Include membergroups". If I click the checkbox from "Exclude members" ony that checkbox is selected and not every membergroup is selected.
You'll ask why exclude all membergroups, I only wanted to send a test email from my forum.
In a certain way proably it has sense to work in this way, but was not so intuitive at first look.
Also If I don't choose to include any membergroup, and I click to "select all" from Exclude members it will select all membergroups from "Include membergroup"
I can remember a thread about this function in the past. There were problems with excluding members from the list.
/me smells bug
