I sincerely apologize; I was unaware of the correct procedure for submitting that request, and as a result, I went about it the wrong way.
I will make sure to follow your advice and avoid repeating this mistake.
Regarding the request itself, I apologize for not clarifying my intent sufficiently; my goal was not to pin the entire “topic,” but rather to pin a specific “post(Reply)” so that it would appear directly beneath the topic’s main post.
However, given that the topic is currently set up in “Wiki” format, there is no need to do that.
(I had intended for the post(Reply) itself to be a wiki, but I consider the current approach—making the topic itself a wiki—to be the most suitable.)
Thank you for your attention and assistance; I will ensure I avoid such errors in the future.
