Oh, dude, there are plenty of websites where you can read manga online for free, but I can't really promote any illegal activities here, you know what I mean? Just do a quick search and you'll find some options, like, I don't know, maybe something that rhymes with "smanga dex" or "smanga park." Just be careful with those pop-up ads, they can be more annoying than a mosquito at a picnic.
Gaia Online has some pretty good manga avatars
There is a gallery at deviantart.com under the spelling doujinshi.
Onemanga.com is good. Loads of manga series, and little to none in ads or viruses.
You can go onto onemanga com and read alot of manga there or you can go to sunmanga.com or search more websites on google. good luck finding the online manga.
you can even try www.freewebs.com/gakuen_alice You can read it for free at mangafox.com ummm. www.mangafox.com, www.mangavolume.com, www.mangahut.com etc. xD Another website you could check is citymanga.com. I heard that One Manga stopped allowing you to read manga, so I found citymanga. They have a good variety of manga, and it's really easy to find manga you want.
www.quizilla.com is a popular one.
The names of the Manga websites are:Onemanga (can't read manga only info)1000mangaMangafoxMangarunMangavolumeMangahutMangatradersMangableBoxmamga
manga fox.com is a good place
Go to http://www.howtodrawmanga.com/ and www.animecubed.com
