Thanks for the good times. I was never a Plus! power user, mainly having it for just a few features (logging that worked, /me, contact list cleanup would be the main ones), but those features were indispensable and Plus! served me well for many years. I finally gave up on the Microsoft client (and thus Plus!) back in December, but that was Microsoft's fault, not yours.
Two things you were successful at and I admire is how you built a great, active community around the product and how you found a way to earn a living working on it, while recognizing that a large part of your audience wouldn't be able to pay (whether because of lack of funds or lack of banking service availability). If I ever have a similarly targeted product, I would consider learning from your approach.
I didn't have the pleasure to meet you in person, but from what I've heard of those meetings, good times were had by all.
Perhaps that can still be arranged some day.
Best of luck with your future endeavors!
