A plugin can return a number that Geeklog will display in the Admin's block. For static pages, for example, it displays the number of static pages in the system. Plugins that don't return anything will display N/A (meaning "not available"
. The Spam-X plugin does that, for example. I guess the G2Bridge doesn't have anything useful to display here, so it simply didn't return anything and Geeklog displays it as N/A.
In other words: This is normal and nothing to be concerned about.
