The moderators have decided to "clean" some sections on the forum that are being exploited by shit posters. Unfortunately whole threads will be deleted, even if there are one or two constructive posts in there. I usually get a message if individual posts was deleted, but when they delete an entire tread, you just notice that when the post count decrease.
Do not feel offended by that, it is just a "house cleaning" attempt by the moderators to control shit posting. This thread will also be deleted, so I just responded quickly to explain to you why this is happening.
