When listening to a weather radio and you hear "spotters have confirmed a tornado" or something similar, that is Skywarn trained spotters confirming it. As of a few weeks ago, the largest Skywarn forum online was powered by vBulletin 3.8 and the second largest online was powered by IPB 4.0. I have since acquired the vBulletin one, merging it into XenForo and then merged the IPB one into the same XenForo creating the largest Skywarn forum on the XenForo platform and knocking out any significant competition. Skywarn Forum is the result Stats: Discussions: 8,965 Messages: 70,698 Members: 5,995 Forum is using a PixelExit theme (Modest) using the red components to match the color brand of the Skywarn organization. Addons include who has been online in 24 hours, media manager, extended like system, tiaga chat pro, tapatalk and nodes as tabs.
