The first post in the S6 Info dump thread is where I try and keep the bulk of the info. Up until now, I have periodically gone and edited the post, as I corrected information or added new info.
Today, I went to add some new info to the first post and found the MODIFY button not there. It is still available on other posts later in the thread, that were made more recently.
So, I am guessing that the ability to modify a post expires after a certain period of time from the original post date. Is that correct?
