Hello,
I have just registered at both places. They are just opening up, but already both excelent sources for information.
The forum is an interesting 'melting pot' for all Power(tm) related individuals, from embedded programmers to TOP500 maintainers. And this was the first place (
http://www.power.org/phpbb/viewtopic.php?t=4 ), where BBRV wrote about the 'when' and 'what' of upcomming Genesi computers.
The power.org membership area is another nice place to visit. Some documents are also available publicly (press archive, news, overview of events), but there is a growing number of documents available only to members. For example, there was a Power.org meeting in Moscow. A list of presentations is available to anyone, but the content of presentations only to members. I would recommend anyone the first presentation: how the Big Blue sees the future of Power!
