What is this setting used for? I have searched and any question pertaining this has always gone unanswered. More importantly, where is it set?
It's not a setting. It stores the highest message ID of your forum, mainly so it doesn't have to be calculated on the fly each time it is used.
Thanks. MKPortal uses this to restrict the topics that can be displayed as news. Which IMO is dumb as all get out, but whatever, I can fix it. Thanks again ak.
