This is another very minor glitch. I think it's great that someone took the time to add a variable and change the grammar when there is only one user online for the message board. I have seen many scripts that say "There are 1 register users online" or something similar. What I have found though is that a user is not recognized soon enough and it creates an error in the display until the page is refreshed or another message board link is clicked. See sample 1 when I first visit the message board and sample 2 after refreshing the page. As the only user I have not been detected fast enough before the page is rendered. I don't know if moving the query further up board.php would solve that or not but another option may be to have the one user output as default and only change the text as additional users are found. I have changed the line
Code:
Content visible to verified customers only.
to
Code:
Content visible to verified customers only.
and that seems to work fine.
