making forum sort issue "stick"?

[Grubbster]

When I visit the individual forums I would like each one to sort with the "last post by" option to be from newest down. Some are that way when I visit and some have no sort option. Each time I visit I have to change it. Anyone know how to make this stick? I am using firefox as a browser. Thanks

The only way to make it "stick" is for Spark to enable it.
Posts are sorted by "thread start time" instead of "last post time" due to abuse of the bumping rules.

Interesting. Some of the subforums sort by "last post by" and some do not. Does Spark have to do this globally or by individual?
ETA: I realized what you were saying. It is the "for sale" type subforums don't sort by "last post by"

Yes. They had to change the sort order in the exchange to curtail bumping by chat.
