Is this website reliable?

I just got my first Notgeld paper money, and was looking online for some information. I can across the website www.notgeld.com and the benefits of registering seem great. When I tried registering, it asks for my address. Is this website reliable? If anyone uses it, what is the free 75 euro worth of Notgeld with first purchase?

Hello,

I have no idea if this site is reliable or not...
Apparently it is owned by this guy " Tony Gibbs-Murray ", who seems to be him : https://uk.linkedin.com/in/anthony-gibbs-murray-5201462b

He sounds quite humble.
