I have been in development for more than 20 years. I remember the story of how Vbulletin died. I was only engaged in forums. One mistake can really cost you a crash. Now you have a choice: leave it as it is or offer a decent solution. As one of the options that I suggested to you.
Please answer in front of everyone - Are you ready to offer us my version? Give the opportunity to renew the license at the old prices for 1 year?
If not, why not?
