Honestly, I have no idea why I got the call, and what may have happened to cause me to get to the top of whatever 'list' WayTools might have. I checked my emails and I had sent in an email asking to join the TREG group in January 2016. Sent a follow-up email on February 6, 2016 with some details about how I might be a good tester (I do a lot of writing daily, basically), and other than that, nothing. I've been mostly lurking in the forums, checking in every few weeks to see what's up, but that's about it.
I'm glad to have been selected for the TREG group, and hopefully whatever testing I can do will help get the Textblade ready for final release. From my brief (under 20min) conversation with the Waytools rep, it really does sound like they're trying to make the product flawless before it's released.
