Good job. It sounds like we're on the same path. I've been creating software since 1980 starting out in the game industry and then business apps including writing and then licensing QuickPay for Quicken to Intuit. Over 70 titles in total.

My #1 program is one that I created in 1999 that works with eBay and I'm still selling and supporting today.

Creating programs and tools that help people in popular platforms has worked out very well for the both of us it seems.
