I've recently heard that the creator and owner of Dims has sold the website to some anonymous new owner(s). Several people over on the Dims message boards have stated that they feel the new owners want to monetize the website further and there is some speculation as to whether all the old artwork and stories will be going away as they aren't very lucrative and just waste space on the servers. I'm not sure of the veracity of all the latter, but the former owner, Conrad - a known FA, did indeed sell off the site. I know Conrad wasn't exactly a popular guy with many Dims users but at least he was truly interested and vested in the FA/BBW community whereas I'm not sure if the new owners even care about the community and only care about potential profits.
I guess we'll see over the course of the next year or so what, if anything, the new owners do with the place but I get the distinct feeling that if there's anything over in the old Dims stories library you'd like to keep then I'd advise copying it to your hard drive.
