Steve,
Hopefully they turn the plugin over to you to maintain. I’ve been using PN for a while and find it nearly perfect for my specific post notification needs. If the do pass it onto you, I have a few suggestions/improvements that I’d love to share with you and would be glad to donate what I can for your time.
BTW- I came here today because for the first time, I had to deactivate the PN plugin due to a snafu. It started re-sending my last email in the queue to all subscribers continually until I deactivated it. It even started re-sending it over & over again when I reactivated PN. Just wondering if you’ve experienced the same issue. The issue seemed to start shortly after downloading the update for Jetpack earlier today. Maybe a conflict with their Subscriptions (post notification) feature? Just curious if you’ve experienced the same issue. My coding skills/experience is very limited to nil.
