Hi Fellow GoLiver! :-)
When GL dropped the DC feature, I was left with 70 sites with no mysql/php system in place. At the same time, Adobe dropped their $499 package for web development. Too long ago to recall but do recall I bought it to get up to speed and it was useless. Then I found WebAssist. The DataAssist/SecurityAssist, and many others, replaced all the GL stuff I was using and had learned over the years. So, yes, fellow GLiver, WA is worth every penny.
But the best part of WA is the tremendous support. I've posted a zillion questions on this forum and always get help. With special issues, a paid ticket gets you top guys logging into your site/database with solutions. All my sites now use WA products and I can't say enough about how I appreciate their products and support.
Hope this helps you decide. And if you are on the GoLive list, say hi. :-) Patrice.
