stocktraderforgain, in April I posted this help for circumventing Yahoo's message board apparent deletions. I think this method will get you what you want, but you will have to try it to see. It works for me each time.
petech, through trial and error and some ratiocinating I discovered a method to have one's posts posted when Yahoo appears to be filtering them. It appears Yahoo has a lot of malfunctions, and that stops posts many times. If you can see your post but your handle does not appear in the latest post column, save your post text then click on the Remove link in your malfunctioned-post, and answer Yes (you want to remove it). In a few minutes to some longer time later, try posting that post again. It has always worked for me, and it has happened to me at least three or four times in the last ten posts I have actually posted. I have had to wait as long as an hour before, but it worked. (of course sometimes I just don't bother after it fails)
I was trying to help others find a more civil board with MNKD information. I guess that one can just search for it as Yahoo must have it filtered out. But that site is moderated and you can get good information there vs this #$%$.
