@jiangcaiyang It works if you do it right. It doesn't take LESS variables, but it does work. Odds are the less styles have higher specificity, so your custom CSS rules are not applied. Use !important or something instead. It will certainly benefit you to not be held back due to incompatibility with newer versions of NodeBB in the future.
I guess some backlash should be expected, new users won't suddenly come out of the woods, so you can only lose some of your active users in the first period after the conversion.
But can we expect 5%? 20% 50% decrease in traffic? And what's to be expected of the situation a few weeks or even months after the conversion? We would move because we think users will stay engaged more with notifications, mentions, modern looks, better usability. We also expect new users to sign up in bigger numbers because this will be easier (SSO) and also because of the improved usability and better looks. But that's all theory so far.
Some real life stories about conversions of big boards would be most welcome
Nice @enriquec ! Awesome to see cloud providers step up and support apps like ours.
Back in the day when WordPress came out, php wasn't supported on web hosts, and they were instrumental in making it the norm. Let's hope we can do our part to make Node apps first-class citizens on web hosts too
