Although I hate seeing a typo or another grammar issue when writing a comment, I do like that comments cannot be edited. Is this going to be a permanent status?
I vaguely remember talking with either your or Becky a few weeks back, and I think we hit on the idea of letting a user have 1 hr to edit or delete a comment after he made it. It just hasn't been implemented yet. Do you remember what iComps did?
Icomps allowed editing at any time, it could be abused at times. People say something unflattering, start a knife fight in the alley and they go back and delete the offending comments...he said/she said stuff..
I think your 1 hour time out will be a good way to start out. I like to fix typos :)
Pinkys comment that when a comment was deleted happened on icomps. "Comment deleted" left a bad taste in my mouth, wondering if someone was hiding bad behavior or such. Unless legitimately removed by a moderator for a good reason.
