Do i need an account on geocaching.com?

No.

Do the IDs need to be written in capital letters?

Yes, as they are usually written in capital letters.

Do the tracking-id of the trackable items work, too?

No, because geocaching.com provides no search ability for these IDs.

Are you somehow associated with Groundspeak?

No, i am just a regular geocacher. ;-)

What is your geocaching-nickname, then?

I call myself simonszu.

Does this plugin have an options page?

No, it is so lightweight that it doesn't need any options.

You are so cool. I want to donate money.
