The "free Community Member class", from what I read so far, is nonexistant and will only be implemented in the future after Linaro is "well-established".
Also, does someone have more info on where the 80 employees number is coming from? As an outsider with a great deal of interest on ARM, I tried searching quite a bit about how exactly the infrastructure for this is being laid out, but so far haven't been able to find much, most probably because it's still quite new and I expect that after the dust has settled this will be fixed.
