Right, we don't "officially" do it, but it's not like we dropped it due to it being too much trouble or whatever. As you said, dropped due to lack of interest. Maybe we should further discuss internally, but if there's interest, then I personally have no problem with reviewing and posting a user submitted tutorial, if it meets the criteria/standards/whatever, and the user agrees to the terms of having it posted. TBH I think a lot of the "lack of interest" was our own fault, for numerous reasons. Virtually no publicizing of it on the main site and no "recognition" on the forums to name a few.
So to make a long story short Ikram, the current "official" way to post tutorials around here is to be active and get yourself promoted to at least guru status. Then you will be able to go submit and have tutorials posted. But I just want to remind you, as mentioned in PM the other day, we will not post random tutorials about java or other random languages, regardless of how good they may be. This is a php focused site.
