Our forums would no longer be on the Internet if it were not for FX's Session Mod. For some reason, after many years of quiet forum use, someone has aimed a bot fleet at our site. Server logs show a large number of IP addresses, so blocking just one won't help. Once we added FX's perfectly functioning (and free!!) Session Mod add-on, the bots were no longer able to overflow XenForo's RAM-based session table. THANK GOODNESS for FX!!
