1. A post may be deleted up to the time a reply is received only. Tie goes to the reply post.
2. Corrections afterward would be severly limited such as to correct spelling, punctuation, emphasis, etc. Changing, adding or deleting content would be a disservice to those who have posted replies based on what was originally written.
3. As you said, an edited post would need to be tagged as such. It should also be bumped by marking it as "unread" again.
To me, the ideal way to do this would be to allow a corrected post to be inserted between it and the first reply but could also be done within the original. It would need to include the entire verbage of the original with the new/corrected text clearly visible to show what was changed. This is just a way to display ones integrity.
There are a couple of ways the Speakeasy could be improved.By improved I do not mean to say there is a whole lot wrong with the Speakeasy as it is now. I just think something good can be made better.
1) Create seperate subsections within the Speakeasy to accomodate and reflect the diversity of opinion expressed and subject areas discussed. For example, a Politics sub-section, a religion sub-section and so on.
I like the idea of creating a sub-section for members to debate one on one. I find it tedious to keep running out of thread space in the middle of a debate and have to start new threads or post off of other threads which may or may not be related and/or have to copy/paste the post url of the person with whom you are debating, into your own reply as a way of maintaining continuity.
2)Allow members to edit their posts.
Put an Edit button somewhere in the thread/post box,require the member to "request"an edit by logging back in. Place the time of the edit somewhere in the thread/post box.This second suggestion could be done in all forums here at CNet.
