Finally I decided to clean up this web site and take a clear decision about it. This website won't be used anymore to publish tutorials, reviews, knowledge, thoughs, articles and so on, but only "projects and products" related to the web site's activity. I removed all the useless categories and simplified alot.
Now you can register an account into this web site, login and leave comments. You can donate to support projects and products on this web site. The software will be really fantastic, so stay tuned because you will see some good ones. Bye!
