  5. The puzzles and crosswords given here were very nice and If possible kindly send me more puzzles & crosswords.

    Thanking You Sir.

  6. I usually do not write many comments, however i did some searching and wound up here Biochemical Puzzles The Biochemistry Questions Site. And I do have a couple of questions for you if you usually do not mind. Could it be only me or does it look like a few of these remarks come across as if they are left by brain dead people? :-P And, if you are writing at additional online sites, I’d like to keep up with anything fresh you have to post. Would you make a list of every one of your community sites like your linkedin profile, Facebook page or twitter feed?
