We already have a workable and working method for correcting blunders. If you simply re-post your message with appropriate correction of errors, you will produce a "duplicate post." Duplicates are cleared when and if they are found, just as a matter of keeping the threads reasonable free of redundancy.

You can also, and should, go to the help page, provide an address for the post and request "I did a boo-boo so I reposted a corrected version. Please delete the first post." I have found that the requested deletions will generally be promptly made.

Anyone having problems with wanting to change what they said should perhaps rethink their "SOM" (Shooting Off Mouth) syndrome. If you said something you shouldn't have, an apology is in order. If you said something that was factually incorrect, then a correction is in order. Common courtesy demands that your apology/correction should cite the error and that the error itself should remain where others can assess how guilty you should feel and whether your apology is sincere enough to be accepted.

If you're saying things that make you feel so guilty that they need to be hidden by deletion, there is a simple process that will solve your problem - it's called "growing up."
