thank you for referring me to a link similar to my post. i am somewhat knowledgeable about the rules in this forum and i know that i should look up first whether someone has already posted something similar to my question. but my problem is whenever i would try to search something from the search bar, nothing would show up. if something would to show up, the results wont be related to my search. i dont know if the problem is from my computer or its a problem here in bitcointalk. also if someone had already posted something similar to my post, should i delete that post?
If you used the forum's bulit-in search bar, yeah, it sucks lol. We typically use ninjastic.space/search or attach "site:bitcointalk.org" using popular search engines e.g. google, duckduckgo, etc.
As for your last question, you can't delete someone else's post. If you were talking about yours, it's fine to just "lock" the thread but you can also delete it if that's what you want.
