Well, Nitin_Tyagi. The guy, sude, did read your post, interpreted it correctly and made the right comment. It is you, however, who missed a trick here!
You posted that users should only submit links to useful sites and then you went ahead and told us not to post links to porn sites. sude wanted to ask you (quite correctly and with due respect, I may add), what made you think that people would post links to porn sites in a thread which was supposed to contain links to useful sites. Think about it seriously, doesn't it subtly convey that you think that porn sites can also be considered useful (so as to expressly bar the posting of such links)?
No offence meant!
