Sumo paint would be a good one. its not necessarily a manga website, but has all different types of drawings. sumo paint has its own drawing application too! Another good one is deviantart.
i prefer dragoart.com because it teaches drawing lessons of all sorts of cool cartoons.
DragoArt.com
Actually, I'm super excited about this but it hasn't hit the manga websites yet. I'm so sad. But u can keep updated and wait then look on these websites Mangafox.com Onemanga.com Findmanga.com U should try Shugo Chara! It's so my fav manga and anime. Then u should try Kamichama Karin or Ouran high School Host Club. There're all great manga and anime.
Quite honestly drawing should be a fun thing, so try practicing the kind of thing you like. If you want to get good at drawing in general I would suggest practicing from still life. Other good starting points are taking pictures and if that is a challenge try making a proportionate grid on the picture and the drawing paper to help make an accurate copy. I consider myself above average in drawing skill but I got there after about 10 years of practice (if you really try and stay consistent, your skill will gradually improve). That's pretty much all the advice I can give in writing, but other options are to observe other good artists you know; use them as a benchmark of sorts.
There are a few programs to make a computer drawing. Some would not agree though on which is the best. So a suggestion would be to try the two following and pick which one feels is the best for them. One is GIMP (free and excellent). The other one is Photoshop (costs some).
not drawing manga... :/

Not really. It depends on what your perception of manga is.
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.
Shoujo, Yaoi, Seinen, Yuri, etc. But it all depends on the type of manga story you will be drawing. For example, if you happen to be drawing a Shoujo type manga story then you will have to be more detailed especially in expressions.
