@ Rahul - Have your Forum Registration points been updated?? And for the participation if forums , do you satisfy the criteria : minimum of 20 posts, 15 replies, 15 responses in a month ... If so , mail the admins man...
Points are updated at the end of the current month or the start of the next month. So i guess you will have to wait till June-15th or may be 1-2 days after that until the points for that are updated.
