How to read the comic:
LJ posts show the comic in reverse chronological order - newest first, oldest last.
The following link will show you only entries containing comics:
Comics, newest to oldest
However, I recommend starting from the beginning and reading forwards. This is imperative in understanding many storylines, as well as for most secondary jokes. The following link takes you to the first comics. (Use the "later" link at the bottom of that page to scroll chronologically).
Comics, oldest to newest.
Also, you can use the "tags" system to view specific storylines or comics featuring a certain character.
One day Ponyville will hopefully have a website, making navigation much easier. Until that day, we shall all suffer together.
