Thanks, Dave. That is a search method I haven't tried yet.
So there seems to be a couple of ways to use this. One way is go to the Forums main page.
Under 'Community', click on 'Forums'
That takes you to the 'Gardening Discussion Forums' which is a list of all the forums. In the upper right corner, there is a search box with the text 'Search Forums' inside it.
Enter your search term. I will use 'Peroxide'
Enter and that will give individual posts as a result with that term.
From here, you can click on the individual Post # to open it up, or you can further narrow your search by choosing a forum from the "Search only in" dropdown menu that comes up under the search term.
Again, by clicking on the post #, you will get the specific post. If you click on the thread name, you will get the start page of the thread, and if you click on the forum name, you will get the main page of the forum.
