Dear Hardeep
Please click on the Recent Post you will find in Right hand side (middle) "Complete List of Forums" in Black colour underlined letters. Click on that "Complete List of Forums". In that screen you select the concerned Category and continued with Forum details. Click on the concerned forum. Then in that opened window there will be two options available in the top left side. i.e., "Start New Topic" and "Share Files & Formats". If you click on the appropriate box then the discussion/comments box will open. Here you can type the headings and further type the contents of the subject/querry/question whatever you feel. Then click on the "Submit New Thread". There ends your posting of new threads.
In short way, You can open any thread from the resent Posts link, see the bottom of discussion/comments box to that thread, you can find a blue box available in the name of Start New Topic. If you click it will take you to complete forum details and from there you can do all the new posts.
Please try and confirm friends.
If you still face some problem never hesitate to call me on 09099024667 while you are in system.
All the best.
