If so, does the content that I posted on here stay on here under my name or does it show up as "deleted user" or something like that?
You can delete all in your post history if you want but your account will remain visible here in the forum.
But it doesn't mean your deleted post will totally disappear, it can be traceable using
LoyceV's tool.
I dont really mind my account remaining on here but the issue being my IP address being stored/logged could cause me trouble in the future. So does deleting my account remove all the stuff I posted?
If this is your concern, so far I didn't see a staff of this forum revealing the user's IP address or privacy, I think it will happen if you will request them.
If not, does deleting this account disconnect this account from those things posted? Or is it still stored/logged? In which case the best I could do is simply remove everything I can from what I posted. I honestly would like to keep those things up... but... Idk if it would still be connected to this account, which was connected to my real IP at one point. Idk.
My advice might be this.
Delete all posts in your history, change your password to a difficult one and forget it.
Leaving in the forum isn't that simple, time come you'll be missed those discussions here. Just preserve your account and come back anytime.
