Links Page

At this point in time, there are only two other MnJ/BoI Pages out there besides Dark Horse's own pages (that I know of):

Leo Sutic's Blade of the Immortal Page -the best for already released BOI info.

John's BOI Gallery  This page has an excellent gallery of the MnJ postcards.  It's better than mine, so I'll be killing my postcard section soon and simply make a link to his page...

Claire's BOI Page excellent comic summaries.

Linsie and Casey's BoI Page I forgot what this page has...
