Good point @Saintseeker
The game rules do not allow players to share links in chats, as mentioned in your comment. This rule is to protect players from following random links, and there's no 24/7 moderator checking each separate link through.
Here on forum on the other hand there's no such rule, and all fan sites or RN related sites are more than welcome here! Good sites or forums about engines... why not!
If you know of good sites, I'd be happy to add those here in this thread!
