now thats something new .. i never read manga's .. i don't like to read in general ... but it's a some usefull info ... good work jess

Well actually I'm done reading Bitter Virgin from Onemanga.com so this is so useful information. XD

Mangafox is amazing... but it crashes my comp >.> Viruses from it twice and killed my friends laptop, maybe my antivirus just sucks though =P

you should add mangastream.com its a good site for a manga lover :)
