I tried /feed and it returns RSS data. Using
https://rssatom.com/, some styling is gone which makes few parts (such as posts quote) annoying to read.
I second to that. RSS is quite difficult to read now. And if it helps, I use
www.inoreader.com for RSS.
I'd also suggest for the topic smaller image at imgur instead of reducing it in the forum. This would make the file smaller and will not have delayed load up.
But, all in all, great job! Congrats!
