12.4 A noun that doesn't start with a capital letter?

From 12.4 extra vocab:

My first thought was that it might be a gerund
(see http://germanforenglishspeakers.com/verbs/present-participles-and-gerunds/ )
in which case it should be capitalised, according to the site linked. 

But I'm not sure; best wait for the experts!

Yes, I think it is an infinitive used as a noun, and it should be capitalised.
I am not very knowledgeable about grammar but in English I think we would call it a gerund.

There are quite a few minor typos scattered around the course and I tend to notice them when revising.

Hallo sfpugh und Peter--252,

You are right about the spelling error in the sentence above. It should be "Matthias ist einfach viel zu pingelig wenn es ums Aufräumen geht…"

The verb aufräumen is being nominalised and therefore should be capitalised. 

Sorry about the inconvenience, I will pass this on to get corrected in the lesson.

Viele Grüße
Julia
