In the url for forum tab on a mod when you select a forum discussion there's a topic_id but you cannot make users go to this specific forum post.
Being able to redirect people to a specific post when they have issue or need specific information would be way better for both modders and users.
e.g https://www.nexusmods.com/clairobscurexpedition33/mods/201?tab=forum&topic_id=15577395
would redirect you to the stickied `GamePass / Epic Games users, help needed !` instead of the main forum tab
The same thing could be applied to comments on posts (there's a `jump_to_comment` when you click on the notifications that a comment was added to your mod), even though I would find it less useful.
