<pre>Tutor IKLEYN: I never saw this UGLY TROLL'S comment as he hid it behind Alan's post. This LOWLIFE even erased one of my posts that I'd directed at JOSGARITHMETIC a few weeks ago. 
I've had confrontations with this UGLY TROLL in the past, and I've gotten to realize that he's a RACIST, SEXIST, and is more than likely mad at the world, especially other people of other races. 
Others (specifically students) have had run-ins with him and do acknowledge that he is nothing but a NASTY, most likely DEPRAVED individual who IRKS everyone, not only here in this forum, but around
him wherever his CAVE is located. He's definitely not worth anything in this form as he tries to run it as though he has any smarts at all to guide/inform anyone.
He's the one who offers absolutely nothing - ZERO, to this site - which has done much to teach me many things since I became part of it. 
If you notice his responses, they are all NASTY and CHILDISH/NITPICKING posts that seem to increase his number of responses. He deserves to be IGNORED because when he wants to criticize someone for not
contributing to this forum, he needs to look at the person in the mirror. Then again, because of his grotesque appearance - external and internal, and attitude, he's most likely not able to. I can bet you
that even his mother, if he has one, HATES his guts.
I was hoping that he'd gone FOREVER when I didn't see him for a while, but the INSECT resurfaced. I hope one day he will DISAPPEAR and we won't have to deal with this IMMATURE and DEPRAVED CHILD, ever again!
Thank you, IKLEYN. If you hadn't responded I wouldn't have known that this RECLUSE was out for my "blood" again!!
