The forum archives are regularly edited to ensure that future readers may easily find useful information. Moderators regularly remove certain threads after a time for a number of reasons, including duplication of subject matter or timeliness of a particular subject. In general, most threads remain online for at least 30 days, so that all interested parties may participate while the subject is relevant to current users. Some threads will then remain online indefinitely, while others will be removed.
Forum moderators have the ability to remove threads at their discretion.
It may have also been flagged for removal for violating community rules by other users.
