*edit*

your question was general, so i am unsure what you really meant, so i assuming you where looking for another source of manga online

If you're looking for another online hosting manga site, try these:

http://manga.animea.net/ (Good but often have poor maintenance thuse leading to spyware, make sure you got your firewall running :/)
http://www.boxmanga.com (You'll find lots of old mangas here, slower updates, but a very vast array of manga selection)
http://www.mangafox.com
http://manga.gamestotal.com (Posts many pictures on one load thus reducing your to click next page)

So many. Google --> Manga Online.
