hi nicolle, i consider the hackers lounge in samacafe as hackerspace. there are other political events in the cafe and the hackers lounge is "only" a weekly meeting, but the free surfstations and the free wlan are available all day. you will find some nerds there every night.
And I consider CCC Mainz as a hackerspace. We don't own the hole location but we have permanently a rent a room. Our room contains a well equipped workshop and loot's of nerd stuff. I think you should be more careful about what you deleting. As you can see on the pictures it is a REAL location and not just a web page. Also we are currently looking for a bigger location because we need more space.
