I've noticed that when I click the "Create thread"button it does not take me back to the main forum view. Is that expected? Because of that I ended up creating a thread twice earlier today.
Here's the issue tracker for the forum, even though it's clearly not a priority for the main developers. It definitely needs some love (at least acknowledging the bugs), as it's one of the main Nim showcases in the wild.
I see. Actually, it seems that the problem is not happening only when creating a thread, but also when using the back button to go back from a thread into the forum. I must reload the page for it to show the list of threads. I'll raise an issue.
