Not added a fancy contact form yet, also not sure if I ever will, I don't think you actually need it to get in touch with me :)
Please do me a favor and don't upload the key to any Keyserver, the whole System seem just to be broken, so I think the best way to share keys is to download it from the personal website or as E-Mail attachment.

But it's not really a big deal, this way you can at least verify that's really my SSH Key, in case you going to add them somewhere to grant me access ;)
