If you are referring to 

 18 re: functional boolean algebra enumeration and  
 19 re: functional boolean algebra enumeration  

 these were both authored by myself (I can return to the IP  209.112.38.~254 to edit this commentary) 
 as stated "... also both 1 and 2 are both authored by myself ..." (interesting Freudian emphasis on both). 

 As for modifying [17 Hoping you can help] as stated above I did not know that, when modifying a comment, if the 'equal equal' top line is deleted then the content becomes appended to the previous comment. It was not intentional and I've apologized also to the author of that compromised comment. 

 So the problem is redundant redundancy from the existence of 18 and 19 that could have been easily rectified if all but the top 'equal equal' line in 18 were modified to reference the new content in 19. (Especially rectified if the 19 clone did not exist in the first place.) 

 Why the wiki environs made the #19 clone I have no idea. Why the wiki commenting environ is so sensitive to this editing error I have no idea. Given the sensitivity, the 'equal equal' line should be isolated on a separate edit field above the main content editing area to avoid this unintentional editing error. (I have since found other anecdotal information regarding this issue on wikipedia with similar suggestions, pro and con.) 

 It was an accident with no vandalistic, destructive or malicious intent. I am too busy assisting and encouraging others in their endeavours and efforts to be subversive.
