This forum can have a setup
"Require authentication to read content on this site, disallow anonymous access."
which is disabled because I wanted the content to be publicly accessible
I try to post news as much as time allows, I probably miss some
but I do think anyone subscribed here could post news if they want
wether that happen or not is out of my reach.
Now "news" does not mean "anything"
I don't want this forum to turn out into a place of advertising for commercial ANE
like you can see on the Adobe Air community on google plus
There is no advertising here, but I have no problem with people promoting their stuff
wether it is an app, a site, whatever, etc. as long as it is related to as3
and as long as it has some content (not just one link).
Having an IDE which is not cross-platform is a not a big problem as long as you build on the command-line, you could use Flash Develop on Windows and Flash Builder on macOS for example.
But the other problem with most of those IDE is that they want to take over the build (how stuff get compiled).
At the second you require someone to have this specific IDE to compile your project, imho you have failed, and this is even worst when it come to open source projects.
Now in the case of an "AS3 to Optimized JS compiler", using Flash Develop as a requirement to use it will prevent developers to debug their project under macOS, Linux, etc. and especially the HTML browsers that are running on those systems.
What happen when your great AS3 app transpiled to JS happen to have a bug under macOS Safari ?
How do you debug your app there ?
