iToysoldiers will notify all club members of new content associated with a gaming club. This is done automatically when an event or an article is "tagged" as club content. There are two ways to tag content as club content.
From the Club PageGiven that you have permission to do so (and most club members will) you can click the appropriate content type from the "Create Club Content" panel on your club page. This will bring you to the screen to create your event or article and automatically associate it with your club.
From the Content Add FormIf you're creating content from your Account menu, there will be a field on the form where you can select the club you'd like to notify. Selecting the club and saving the form when you are done will send out the notifications.
