While you won’t be able to edit your posts forever …
At first read, that sounded like a feature that is slated to be sunset.
How about changing it to something like: “While new posts can only be edited for a couple of hours after creation …”,
or even “Note that new posts are only editable for a couple of hours, but during this window, editing is encouraged …”
Thanks for the feedback! I agree that could be interpreted as “we won’t have this feature forever” when that is actually not the case.
This is a built-in badge with a default description from our forum platform, Discourse, but I was able to update it! Let me know if it makes more sense to you now.
