San - I haven't gotten a chance to say this before so here I go - thanks for the great work you have done over the years for Sajha. To your point of a user changing his or her mind after posting, any thoughts on having an "edit" function that a user can use to edit a previous post? I have seen this on some other discussion forums and it is particularly useful if there have been typos and misspellings in your post ( I am sure it has other benefits too) . Just a suggestion. Regards.
