There is no limit on the # of pages/post in a single thread that the website can do. However after so many pages/post in a single thread the website database begins to 'slow down' so the MODs will lock and start a new thread to ensure that the 'slowness' is not experienced.
Look at the unofficial status updated thread and how many parts that has to understand the concept.
Something like 5000 posts. The mods broke the NWI general thread into two at that point. Helps the database or some such.
ah i see thank you folks! makes sense i figured there would be some kind of a size limit due to performance. but i didnt know how to word it......
thanks again
