Well, no member is restricted to post content on this site unless the quality of the content being posted by a particular member happens to be completely of not some good quality to suit the needs of the site. Please note that I am not saying that the content is bad - there is always a difference between bad and not so good. If you are restricted from posting in any particular section, you are advised to improve your skills and keep contributing in other sections so that you can prove yourself. Once you think you have enough content to prove your ability, you can request for removing the restricted access. It can either be done through a thread here in the forum section or you may also opt to get in touch with WMs.
Live....and Let Live...!
