You can simply write me an email, if you need to. Be aware that this account is public, so very crowded. Also, see below for a link to the imprint and data protection. By sending me an email I expect you to understand that I need to get your email address to answer you, and your name to be friendly. Be aware that I do have a right protection insurance, so if you really need to sue me on that, we’ll fight this through and get it clarified. See data protection for understanding that I save your name and email address.
