Good link, a 5.

It's getting a bit late, but... have you seen my 1st of April publication yet?

Hope it can add some good mood for you; and your could ask me some difficult questions, as other members did. :-)

Thanks Sergey.

I briefly read through your article, but before that I had seen your post in the Suggs and Bugs forum where you mentioned you planned to submit the article on April 1st, so I kind of knew where that was going :-).
I do have something to add to the discussions, but I have not had time to gather my references yet.
