Also,
@Calif_Sue , if I happen to make any posts, then disappear for days, and that post seriously needs to be fixed like the above one , please feel free to fix it if you as plants_admin have that capability. I certainly don't want to lead viewers astray. Thanks.

P.S. Also, if a tutorial for navigating NGA is not already available and I missed it, perhaps it could be titled "Navigating NGA"
