To the right of the writing window below the smileys is "BBCode is ON". You see the underline if you hover the mouse over it. Who would have guessed that behind this are the instructions for using the forum writing tools? The URL even includes the word "help": app.php/help/bbcode !
I suggest this text is changed to read "
An even better solution would be to place the help button above the writing window with all the other buttons, preferably on the left end. It would be more likely to be noticed there and a button is obviously clickable. The buttons do have hover text, unlike BBCode.
This may seem like a minor gripe but it isn't. I have studied computer usability and such little things can make a big difference.
