The "MoinMoin:YourName" part was intended to be interwiki-like notation (WikiIdentifier:PageName). As your wiki page is called "MiksKalnins" on the wiki, you should remove the blank.
As your email address is also on your wiki page, it might be easier to have it there only, so you just need to fix it there in case it changes. If you prefer, you can also duplicate it into the (c) header, your choice.
