Honestly, I just purchased this app to do a reset a while back and during the process of getting ready to upgrade to 4.5 I noticed the app wasn't updated.
Upgrading it is totally up to you. If the feature is in IPS and your plugin doesn't do anything beyond that, then retire the app. If you can make money with a feature beyond what IPS provides, then sweet go for it. Bottom line I just needed something to force a password change. Since you have the app already done, add a few features and make some easy money.
Maybe add a frequency. Meaning I can automatically require Newbies to reset every month and Senior members to reset every year?
What would be neat:
1. I initiate that X group needs to reset their password.
2. They need to reset the password in X months, year, or set amount of time.
3. If they don't reset their password, then they are marked as a dead account and moved to a special group.
4. If they haven't changed password in number 3 above and have ZERO content = delete member.
Just an idea. Nothing that I can't live without if you just want to retire the app.
