Can we have longer to edit our posts?

I see that I can not edit some of my posts that were made more than 18 hours ago. Can we lengthen the window during which posts can be edited, to perhaps forever?

This was the way things were on the old forum and I do not recall it causing any difficulty.

I personally struggle with writing clearly and my typing is atrocious. The ability to go back into an old post and clean up my grammar, increase clarity, or make some corrections on a posted character would be really valuable.

Done. Let me know if you're still have any trouble with it.

Thanks so much.
