:salam2:
I apologize for not getting to this earlier.
- Ahsen: If the site is soley just Qur'aan such as Quran Explorer - or its likes etc, then it is okay inshaAllaah. However if it is more than that and has explanations of its own (aside from the recognized and accepted modes of tafseer) then it is not allowed, along with if it is linked to a certain organziation or spammed in many posts.
- mhassan10: A few Users have had this problem. You can search the "Help Using Website" section of the forum to find related problems that might help your situation. Many times in this case - regarding posting threads, it's just a glitch of sorts, or perhaps with the database, and usually if the User changes the title of the thread and tries posting it again it will be accepted and go through.
I hope that works for you inshaAllaah.
