I’m terribly tired and irritated to look through tons of spammy comments. Dear spammers! Your comments will NEVER be added! If you comment is really valuable, it’ll be added without your link and only if your link can be useful for our community, it’ll be added, so first think then write.

To the readers of the blog: If you have posted a good comments and it was not added, write me to e-mail and we’ll discuss it. Sorry, but 1 good comment can be lost in several thousands of commercial ones. Tc, John.
