basically posting in the existing thread saves coz merging it.
many of us like to subscribe to threads so we're kept up to date, as we don't always see new posts. also if we have to subscribe to multiple threads, when do we remember to delete the old subscription.... recently there was a site-wide cleanup of subscriptions, as they are a heavy load.
anyway, glad I know about the new version.
@not_a_Stain - I just use the gps camera mode, when I want gps tags.
