Hope you weren't making a lot of stuff from Magknits! Kerrie pulled the site down!
Ravellers can be happy as various of the designers will put the designs on Ravelry (search for Magknits and read the threads) and the Island of Misfit Patterns has offered to host patterns there (handy for non-Ravellers). It will take a bit of time though cos various of the designers are going to reformat the patterns into PDFs etc.
In the meantime, you can google for the pattern name and look at the cached version (no pics though cos that links to magknits).
