Yes I am aware that the Mepisguides.com site is still down. Those needing to access the site can find Cblue's mirror at http://www.mepislovers.org/mepisguides/. Unfortunately the previous host simply ran out of room to host the site.
For future guides I'm looking at other solutions such as using Google Image to host the images, something I've been working with in this blog on a regular basis. That should take the pressure off hosts for future updates. I currently do have a line on somebody else offering to host the site, so hopefully Mepisguides.com will be back up soon.
