Site policy is that threads are not generally locked until they reach 2000 posts. By starting multiple threads that the only purpose is to reach half of the life of the thread only serves to clutter up the server.
Therefore, if you wish to continue "counting" threads, the goal for each one should be to reach the 2000 mark, not just 1000. Therefore the title of this thread will be changed to reflect that decision of the Moderating staff.
If you wish, there is also and ongoing "Count to a Million" thread in the Fun and Games lounge on the main board, which is currently on its. XIV (14th)incarnation.
