It's looking like in the future there will be significantly more posts that have nothing to do with landscape or garden design posted here. I don't usually create threads, but in creating this one I see that Houzz FORCES you to select at least one other category to cross post in. (I'm picking "Using Houzz.") At the upper right of each post there's a small grey flag. If people start regularly flagging these posts as "inappropriate," Houzz may get the message and do something about it. It takes just a second to do. If they're true to their word, a human will have to take a look at every flagged post and make a decision about it.

Also (and admittedly I'm guilty of this) I think it would be good policy not to respond to or answer any of these erroneously posted posts, even if one knows the answer. It's kind of like feeding the bears at Yellowstone.
