I see you wrote that you’re thinking about making it FOSS. What’s the alternative? Paid software/non-free license + Open Source or proprietary? If you’re low on time and don’t have the capacity to maintain (bugfixes/reports from users) yourself then I say proprietary is a no-go. Then about the license - IMO (though I don’t have hard data on that on hand) people much more likely contribute to FOSS as opposed to locked in license + open source model.

On the opposite - version 8 is great.

The example you gave is a bit unfortunate - the word “Nazi” totally lost it’s meaning and the scope is ever increasing - it’s not more “bad/evil” nowadays. It’s like people forgot another words when disagreeing with someone. It could be you being banned as “nazi” some day and some chump will (mis)quote the paradox of tolerance in comments and pat themselves at the back for all the upvotes :D After all, nobody likes Nazis, right?

Why the switch to XMPP btw?

Do you know what game is that from?

As both user and developer - user CAN contribute but the developer/maintainer SHOULD add the screenshots.
