Jay,
Are you looking at a forum called Tips & Tricks in each Category like questions on mowers, Questions on Trimmers & Brushcutters etc?
It could be a bit involved as people would end up asking questions in that area which would make it the same as the other post.
I think it would have to have an area where the moderators would have to approve all post to make it beneficial to all members looking for how to fix something.
Good idea and worth looking at to help members but we need more information on which would be the best way to set up each topic.
