Could one of the admins here set “post edit time limit” to 0 to allow us to edit/correct older posts?
We can still delete old posts, but that is a bit harsh.
Or is it a deliberate choice that all of our spelling errors and misinformed statements be preserved for eternity? 
If that were possible I would replace the majority of my posts with:
[post withdrawn will be deleted within 24 hours unless flagged]
This. Discobot and the developers would like to drive us slightly mad. Just think about the annoying messages that we shouldn’t talk too much to each other …
Just imagine a place built for communication that actually encourages you to communicate!
MOST UNORTHODOX!!! 
Indeed!
I don’t think the time limit is a bad thing. Then we don’t have the option to ovethink things and think, “what if everyone remembers that typo I made six months ago?!”
Also, I think anyone mentioned in an edited post gets a new notification. And it might bring the post to the top of the forum as well. Is that correct?
I don’t like it when people remove or add information in months/year old posts.
Yep, sounds fine to me.
Yes, and that’s why the poster would think twice about changing his post. 
Sometimes it is hard enough to read posts that keep getting changed as soon as they are published. Something I´m not entirely innocent of myself but I´m especially looking in the direction of @Gffp here…
If I has to writ tinks as thei came ot of mi fingers at first attempt, they wuld be so iasy to undersand…
As soon as I recognize a typo, an error or a incorrect information, I usually correct it.
But what about blurring out a spoiler you didn’t blur out?
Or correcting a real error that makes you look stoopid. (not just a typo)?
I agree the use of it should be very limited, but I came across a few old posts of mine (looking for something else) that I would like to change.
Otherwise I will remove them.
9/10 of my posts contain edits for stuff I forgot and/or the obvious typo corrections within 2 minutes of original posting.
veryr eaiy to sme
If it’s really a serious issue then delete the post and make a new one.
Stop changing history. Make a better future instead.
So what do you want me to do with Baby Hitler now?
With this haircut? We are all doomed.
So in order to make a better future…kill all babies with bad haircuts to prevent potentional mass murder?
Sounds like a plan.
If he were born nowadays, someone (lower case) could teach him not to play with gas. It’s dangerous.
I can see Kate replying right now and I bet you she´s gonna say something about fixing typos…
