To the visitor.


At this forum, &nbsp;there is a &nbsp;POLICY, &nbsp;a &nbsp;RULE &nbsp;and a &nbsp;REQUIREMENT:


<H2>&nbsp;&nbsp;&nbsp;&nbsp;ONE and ONLY ONE problem per post</H2>

Those who violate this rule, &nbsp;work &nbsp;AGAINST &nbsp;their own interests.


In particular, &nbsp;if you do violate, &nbsp;you &nbsp;ALWAYS &nbsp;will obtain the answers from the &nbsp;"tutors" &nbsp;of that quality, 
as you get now from &nbsp;@mananth.
