Did you try recently, like today? I did a few tests and the uploads succeeded:
I also tried as a normal, non-admin user and it worked.
I'm not sure why it wouldn't work. Maybe it has to do with your image. Can you post your image on https://imgur.com so I can try downloading it, then uploading it here?
Is the "Bugs" section intended to be under "Runtimes"? I ask because the stickied "Bug posting guidelines" thread outlines the process of reporting Spine Editor bugs, not runtime bugs. So it's unclear to me if this Bugs section is for the runtimes or the editor.
I also have something to report: after reading a notification it remains there on the bell with the number.

It doesn't go away even after clicking on the notification itself, which should tell to the website, beyond reasonable doubt, that the notification has been seen and read.
Also I have trouble too uploading images. The upload button gave me error after selecting the file, telling me to refresh the page (did it and no luck)
I couldn't even make it work through direct linking the image, the preview shows that the link diseappears but no image appears in its place. Might just be cause I don't know how to do it...
Fabiano Regarding the notification, you can reset the notification by pressing the check button:
In fact, I also feel that some of the features of the new forum are hard to understand or notice, so perhaps we should have a guide on how to use the forum.
Regarding uploading images, you should be able to do it by simply dragging and dropping them into the text field. If that doesn't seem to work either, please let us know!
We've fixed some image/file upload issues, should be good now!
The notifications are a little odd. They seem to turn gray when read, but they don't disappear for some time. I guess that's so you can still access them, rather than have them disappear.
The US has an "amber alert" system. When a child is abducted, they can use it send a message to EVERYONE'S cell phone in the area with a description of the car and abductor. That's cool, but it makes a terrible screeching noise and shortly after it starts speaking the text of the alert. If you click OK to make that stop, the alert disappears completely! That basically encourages people to just click OK to make the noise stop. 
Anyway, maybe notifications sticking around isn't so bad. 
Can we get an option to either delete threads or edit thread titles in case of a typo?
@T.Fly() You should be able to edit your post (and the title) for 10 minutes after posting. Oh, changing the title is a little tricky to find. It's not editing the post, it's "renaming" from the list of discussions: Image removed due to the lack of support for HTTPS. | Show Anyway
