sir: i asked you repeatedly not to  write the whole post in a single line.  but you seem to ignore that and even  don′t give a comment. what a pity!  now i just ask other members of the  forum not to answer your posts.

why absolutely no communication?  maybe you have reasons for that what  you did, then tell us! let us understand  you!  it′s not my purpose to boycott you in  this forum! we should only respect  each other. i do what you request and  you do what i request. that′ the rule!
