Not sure if you'll be notified about my reply, since I'm not replying to your parents and I mentioned you in an edit which I don't think counts :P
See above (below? I dunno I have included screenshots lol)
But really I make that mistake all the time trying to find tag posts by using the top search and then remember I have to use the 'topic' search.
Apparently we didn't do every single tag to save a bit on our end. So not every topic will show up.
