Imgur recently changed their TOS. Please click here to read it carefully if you do not understand the rest of this post.
Forum hosts are being blocked because people are using Imgur to host images that "represent" their forum. I do not host any of my images on Imgur. However, many of you are using Imgur to host your avatars and signatures. The only time you can use Imgur on this forum is to share an image within a post. It cannot be used in a place that will be reloaded multiple times per day. If you do not rehost your images yourself, I will have to delete them. I will not rehost them for you.
