If you've popped over to Blastwave.org in the last few days you're likely to have encountered this...
I don't know the exact reason for this, but if the comments on the various forums, eg comp.unix.solaris, are anything to go by, it's such a shame greed has got the better of a great resource.
I've never been a big fan of Blastwave (too many non-Solaris supplied dependencies for my liking), but I know many other people are fans and use it quite extensively, but hopefully Dennis or Phil Brown will release an official statement explaining what's potting.
Update: Unofficial update from Ben Rockwood (an outsider like the rest of us). Looks like things have got very smelly between Dennis and Phil :-(
