As @marstato already mentioned, your suggestions do not sound natural and like @RegDwight mentioned camel case is not proper capitalization in German (unless we write source code).
And I don't think that an unspecific "Liste meiner Dinge" is a good choice for a title or headline.
If you mean a list with the top 10 reasons for a specific topic then you could build a specific headline like "Die 10 (besten) Gründe für/weshalb/warum [your topic]". This is not concise but this is how it is mostly done to have an interesting title.
EDIT: Now we know it should be a more or less short term used for only one subdomain name regardless of any topic. I don't think that we have a good short term in German that implies your "list of things". So I advice just a lowercase version of Sammelsurium = "sammelsurium.yourdomain.com" (mingle-mangle, similar to "Kram" or "Mischmasch"), because it sounds better than "Dinge", "Sachen" or "Liste" or any combinations of these, but it's unfortunately still unspecific and not the same as your english term.
