Hey Cesareo,
I wrote it some time back and have no use for it anymore due to the use of intranet-contacts to achieve most of the functionality, so yes, it probably is deprecated from me, but feel free to work on it 😊.
If I remember correctly I wrote a code piece which shows the current subscribers. Just make a grep for "subscribers"
Link Tracking works as well as view tracking. But I think you need an additional package installed for that.
Sorry for the not so detailed answers, but it has been a while ago that I worked with this code ....
Cheers
Malte
