Wanted to make sure I'm NOT going to break forum rules

Hello all,
This question is more aimed towards moderators.

I was thinking about helping to keep the forum optimized for searching by new users. To do this, I was going to go back in my Tracked Threads and choose Best Answers for ones that haven't had any activity in more than three months. Is this against forum rules? Do you or do you not recommend this?

Thank you for taking the time to help a fellow user.

You can't select the BA unless you're the OP. Periodically, a moderator will go through older threads and select the BA to close the thread out. It usually takes around 90 days.
