I am getting used to the new format and I like that I can now give a thumbs up to posters while on a mobile device; however, I would prefer more than 24 hours for the edit feature. IIRC, we had weeks to edit posts on the previous format and we did not suffer spam issues.How To Edit A Post
You should be able to edit your post for up to 24 hours. Near the timestamp at the top of the post, you should see an edit link if it is within that time limit. After 24 hours you would need to reach out to a mod/admin for assistance.
Time limits are used in order to preserve useful thread content, while also protecting the forum against spam. We have formulated the current times in a way to best prevent thread confusion and time gaps left vulnerable to spam.
