I, too, have been blocked from using SUMo,. In fact, the KCSoftware website is blocked, and the KCSoftware Forum site has been blocked. The only way I was able to contact them was through email, and so far have not yet gotten a reply. Going through your help file, I was able to find a way to allow the website to be ignored by your blocker, but I do not like doing that as I may encounter one of the dangerous sites hosted at this IP. I realize that you feel you must block this IP, but wonder if there is a way you can block only the dangerous sites at this IP, not the KCSoftware sites?
