So you have to change your website in 60 days, but sage doesn't announce it to the world until November??
Well, I always bitched that sage never marketed any products, just their brand. We got our wish....And unfortunately, you now know that the solution you support is officially 'legacy' and not going anywhere if they aren't willing to put a dime into advertising it.
If you are seriously loyal to Sage I suggest you bone up on your French so you can master X3 and its underlying data tables. If not, time to look at some alteratives...
