No hassle at all, and as I noted they're mostly little nuisances and don't break the forum in any way. I'd say that the last one is probably the most important as it actually relates to the usability.
Yes uploads are turned off (at least should be, but some people reported them as working)
If you can use Gravatar, that is our preferred way to get pictures here.
We will look at the uploads on the next update, but for now the admins are busy with other systems again. (uploading stuff on cloud platforms is complicated enough that I rather have professional figuring out what the problem is)
Yes, we seem to have issues with the infra. It is being worked on, and we really hope to get it solved soon.
It all comes down to traffic increasing steadily all the time, and we need to keep up with that.
Yes, the words are unfortunately not standard.
The latest nodebb themes seem to hide the favourite tab to the topic menu, which makes sense.
But we could still change the voting buttons to thumbs up and down or something more sensible.
Also hints on mouse-over would definitely make sense.
I'll ask when someone here can hack our theme to include those changes.
You pretty much have the answer to your question there.
SO does not help one bit in keeping a community together. Also fragmenting the services does not help in that (Q&A in SO, other things here), and people would probably still cross post to both (or shout for a Q&A area here).
I don't see having multiple Q&A forums an issue (there's Qt centre, Qtforum, Qt apps, Qt developpez, Qtfr, and other local sites too). The thing we try to do here, is to be a place where the community can come together, talk and ask questions among other things.
We had a server malfunctioning on the weekend, it was crashing at regular intervals. And as we are running a clustered setup for the forum, every time the server went down traffic from that node went to the other nodes, and that looks like an update (taken offline, and brought back somewhere else) to the forum software.
Sometimes the load balancer does the same trick and you get the message if you keep a window open long enough.
But the message is completely harmless.
@JKSH As indicated above I have use other search engines to find what I am looking for. It escapes me why you would want to abandon something that is working, for something that is practically useless.
