One bad etiquette that doesn't happen that often on this site, but on some sites it's prevalent is "quoting".
Seen in this thread as a small example is post 27 by un-named poster. The post he quoted was the one above. Easier to just have said; Kiwi, I agree...... Bla Bla Bla
Post 22 in this thread is acceptable, because it relates to the original post on another page.
I have seen on here were someone posted five or six images, and 2 posts down someone has quoted the whole thing. How darn annoying...
Thats my bad etiquette whine.
