Editing posts after being un-banned

I think this question isn't covered by the rules posted, that's why I'm creating a new topic. If it ~is~ covered there, please tell me, I didn't see it o.Ó

So I was recently un-banned, and watching the posts that made me banned, I was wondering if I'm able to edit them to include (kind of more) relevant information. Am I allowed to do so, or do I have to let them the way they are now?

Thanks in advance, and thank you for un-banning my account~ ^^

it's a great idea!
