Not a replacement request, but given that the post replacement feature will now soon be bumped to only Mod+ privileges, now is a better time than any to request that your misplaced posts finally be taken care of. I am not a Mod at the time, so it will no longer be in my power to.
This came probably because of both unintentional and intentional misuse of the feature given the above linked discussion. I sincerely apologize to everyone here, especially to those who've asked me in the past to replace their posts privately and publicly without fear of their posts being succeeded (such as through the uploads of other greedy users).
Despite this, however, you could support topic #14446 if you're having particular trouble recovering your upload limit.
