Didn't know if I should place this here or in the member artwork section but...
We all know MegaTokyo, but there are many other great online manga that I have come across on the internet. Here are a few:
TimeScapes - http://www.neondragonart.com/ts/
9th Elsewhere - http://www.greenhaven.net/9e/
Sky Fall - http://www.skyfallmanga.com/
And my own Xamra - http://www.xamra.com
These guys are also members of RazorComics, which has other manga influenced online comics. http://www.razorcomics.com
Sorry if this sounds like an ad. No one is making money here. I just thought you guys would enjoy these. So please don't hit me. (covers head)
