Post# of 96879
On the Main NTEK Board Page ... Look at the AREA just above where the all the POSTS are listed ... above where the Stickies would be ... the same line that shows "Create New Post" ... "View All Posts" ... "Banned"
If you see a "Green + / Yellow Star" Board Mark selection ... then you have NOT "Favorited" or "Board Marked" the board.
If you have already selected that ... then that selection is NOT shown there and that Board will be listed under the Investors Hangout "Favorites" along the Top Blue Banner ...
So the "Board Mark Count" listed at the top of the Main Board Page just indicates HOW MANY have made that particular Board a "Favorite" ...
