I am only a very occasional visitor to this board, so I am not acquainted with the accepted "culture".
However, I do know the Global Rules and also all of the board specific rules.
There is absolutely NOTHING in the Global Rules, nor in the /cm/ Board Rules that REQUIRES:> "... five or six images ...." ;
to be posted by OP in order to start a new thread.
The comment in the "sticky" is quite clearly:
just an advisory request, specifically:> " 2. PLEASE post 5 to 6 images to get new threads started. "
(with my upper case emphasis)
It is people like you [ >>3329030
] that make reasonable people like me so reluctant to visit this board any more than once every couple of months for half an hour or thereabouts.
