Another (pay) site is closing down again, this time it's SimPlosion. They went pay some time back as the owner could not pay the bandwidth bills anymore, unfortunately. But that's not the reason the site's being closed:

"I would like to thank those of you that supported me and stuck by me, unfortunately my heart is not really into this if I want to make stuff I will do it when I want and for the fun of making it, because I want to not because I feel I have to. Where is the fun in that?"

The PayPal button where you can sign up as member will be removed tomorrow, 14 February. That means you still have a very short time to sign up for just $2.49 to get their files. They're the second site that I know of that's closing this weekend, SimFever (a paysite too) being the first one. The free downloads of Simplosion will remain available on their freebies site. The complete newspost about the closing down can be found at the updates page.
