Sometimes there are duplicate threads.

Space can be saved if users can delete their posts if they notice others just like them.

Also sometimes people may say things then change their minds about something and may want to delete his or her comment (again, saving space)

In short, A way of deleting Comments/Threads is just necessary.

And I'm sure every forum member would agree to this.

Just make sure to fully tested before adding it if you take this suggestion.

It'd be bad if someone went around exploiting bugs and deleting 75% of the comments and threads here

Can be done, is there a thread you need to remove right now?

 Nope, nothing really important. I was just suggesting this for the general community

Although, if I had to say one thing that gave me this idea. I'd say that this guy may need this feature. I'd ask him though https://swdteam.co.uk/forum?p=thread&tid=229.

The post title was something different, but it's literally just a thread saying "nvm" now.

I agree with this, everything you said sums up the situation pretty well. I give my full suppourt.

Maybe the user is only able to delete his/her own posts and comments, we don't want standard users running around with admin powers do we? ;)

Well, this one now

I posted it in the wrong section and now it's just wasting space at the moment

 Yep. They'd just have to make sure no normal users can somehow bug their way into getting the "admin version" of it
