So, about the suggestions:
-Themes: Perhaps a darker theme could be useful for the site? Some people tend to prefer a dark background/light characters combination rather than light background/dark characters.
-Forum Browsing: Limiting it to 10 threads per page is a bit too little. Perhaps it could be expanded to 15 or 20, or make an option to change how many threads you see per page? (Unless I've missed it)
On user reviews:
-The rules of the site include no advertisement. However, what happens if a youtube video link was added, for example, to a videogame's boss fight? Would it count as advertisement?
Thanks for the attention.
