I noticed that the reply button (when replying to a post on forum, not the topic (main post)) redirects to the home page. I think it shouldn't be that way, but probably quote the user we are replaying to.
Also, I don't know if that's implemented but a mark (like the tick on Twitter for verified accounts) standing with the user accounts of official profiles (like admins or HMD employees) would be great, because I already saw a user called "Nokia" and that's probably not the official Nokia (or maybe is?). I see the mod has mod written so maybe that's already solved for all "HMD" accounts.
Would be smart restricting usernames like Nokia etc when registering.
