I've just put this list together myself and have checked each link. If anyone wants to add this list to their website, I would prefer you to link to the thread rather than copy and paste the list straight onto your website. Either that or you could provide a link to this thread below or above the list on your website so that people know where the source of the information came from.
Anyway, I'm sure there will be more Press Release sites to follow this list, which will be from other people that will post in this thread.
