"(Note: I was unsure of what package this is found in, so my apologies if the
selection I made is incorrect).

Basically, this is just a simple writing error in the "share folder" option in
Nautilus. When you right click a folder in Nautilus and select share folder,
there is a space missing between two of the words before the end (if anyone
reading this can't spot it, I'll post the exact text). Not a big problem, but
not professional looking either (unfortunately it came up while I was
demonstrating Ubuntu to a friend :>).

If someone could take a look at this and change it, that would be quite
helpful...also, though I'm not sure if it makes a difference or not, I'm using
the English(Canada) language setting as default.

Since it struck me as silly not to include the actual text, it's "modifyyour"
(it should be obvious where the space is needed ;>)."
