Hello, I am a big xkcd fan.
 My introduction as xkcd fan
 I'm not native English
...and I do not like "typos". So many THANKS for helping on this issue or even more important: Wrong grammar <-I don't like this errors I didn't see.
As a German native speaker I had to learn something like "Oxford English" in school, and I hated it. My knowledge about the (American, British, more...) English language mostly belong to later experiences. International contacts, science (especially physics), programming (Randall does not know how funny IBM does translations for German, "Copy from To" is in German just "Copy Until"), AND the main language at the internet of course is English.
Also I was even bad on the German language sessions at school. But that's just an other story.
I'm happy about corrections on my typos and grammar, but on essential content I will discuss.
