There exists the demand for a more casual, agile, chatlike community and it can coexist just fine with the more formal, archival forum.
Most of the top Shadow Empire players and community contributors/guidemakers/modders/artists are active on the Discord, and some of them don't even have a forum account.
Do you see how the end of your second sentence undermines the end of the first ?
I don't see what the problem with Discord is. For SE it is extremely useful as you can distribute saves very easily and quickly and let's be honest, these forums are very antiquated and hard to use. I couldn't imagine playing SE without some software that lets you drag and drop files and ping the player in an instant.
I listed the two classes of issues with Discord in my previous message.
While the Matrix Games Forums are quirky even for ASP.NET forums, you *do* realize that we're discussing a game with an even older style (late 90's compared to early 00's) ?
And ASP.NET / phpBB forums are in general definitely NOT hard to use; not to mention : what other kind of long-term, long-form alternative there even is ?
No, the main usability issue with these (sub!) forums is the way too low file size limit (& filetype restrictions ?) - I hear that other Matrix Games subforums (like Distant Worlds (2?)) have *much* more lenient limits, so Vic should look into fixing that.
Finally, I have no issues with Discord's features - they're great ! - some people say that it uses a lot of memory, but it's still very impressive (and snappy!) for software based on something as inefficient as the Electron framework (which pretty much runs on a virtual machine inside a browser !).
My issues are with the ethical concerns listed in my previous message.
And it's not like there aren't plenty of alternatives, for instance Matrix (no relation with Matrix Games) / Element is pretty good these days, and doesn't have the ethical issues of Discord. (But even with Matrix there would still be an attention issue if people started to spend most of their time discussing the game in Matrix rooms, rather than here.)
(Also, *technically* even e-mail fits your requirement of "some software that lets you drag and drop files and ping the player in an instant" - remember what PBEM stands for ?)
