I would like to suggest adding more options for comments (including comments on guides, workshop entries, personal profiles, and more).

From what seems relevant to me:

1. Add the ability to respond to comments. For example: a user wrote something to me in the comments of a profile or a guide - and I can click "reply" next to his comment, and answer him specifically. And everyone will see to whom my answer is addressed. And even if he changes his nickname, or there will be many more comments later, it will be easy to track my answers and the answers of other users.

2. Add the ability to change comments. For example: Now, if I made a spelling mistake or didn't write something, I either need to write another new comment-addition, or delete the previous one and write a new one. Yes, this can be abused by radically rewriting the message. But I think more people will still use it for good.

3. Add the ability to rate comments. Perhaps adding an already existing reward system. For example: A user wrote a very important comment on my guide that helped solve a problem that I had missed. I would like to reward him, or at least give him a like.

* Interestingly, on the Steam forum, all of the above works great (I did not know this). Perhaps it would be worth just using the already developed mechanics in other sections that I mentioned. With one exception: a new comment must be placed at the very top, not at the bottom.
