That is a fine link to the temporary (I think temporary) replacement Forum while the one hosted by Murga is down. It is very important to try to hold the peer-support community together.
I don't know what is the history of the hate-fest against Puppy in general, and Murga in specific, it is very sad and is a terrible waste of time and energy.
Meanwhile, I have been using many different Puppy puplets for many years and have always found the folks on the Murga-hosted Forum, and Barry's blog, to be helpful and Puppy a wonderful resource.
Fluppy 013/Puppeee were amazing contributions for netbooks and laptops from Jemimah, but her military duties made it impossible for her to continue. Squeeze 5x9 is also a wonderful puplet, and I believe they are about to release a version for dual-processors. For 64-bit there's Fatdog and LHP (I forget the version).
Stay the course and ride-out this temporary storm - there are more good things ahead for Puppy Linux!
