I wasn't quite sure where to put this, so I decided this would fit.

Now, I'm no newbie to tabs, don't get me wrong, for I've written several ones myself (mostly jazz stuff).
However, I was attempting to learn a Bob Dylan Song at this chord layout (http://www.ultimate-guitar.com/tabs/b/bob_dylan/talkin_new_york_crd.htm) and have several questions about the author's notation.

1) What do the periods, such as "G . C . D . ." mean? I assumed it meant repeat the previous chord.

2) What do the slashes such as "/B" signify?

3) "(. /E/D . )" Parenthesis mean alternate ending?
The periods appear to be spacing out the chords.

The slashes probably mean nothing. Maybe a bar change or something like that.

Whoever posted that did a terrible job at formatting it, by the way.
Q: Favourite Pink Floyd song?
A: The one where they get wicked high and play Emin and A for an hour.

The pit won't be able to help you...sorry!! by the way E/B mean that you play an B chord but with a E as a bass note!

I know that, I'm in multiple music theory classes.
However, there are a few places where it is just, for example, "/B", no other letter in front of it.
