Anime 2 Manga Forums

I am a manga artist and I just got a new art room in my house. Can you suggest any site that has pictures of manga /anime studios and a list of products I can refer?

I don't know about pictures of studios, but information about companies can be found on their web sites. For instance, http://www.viz.com has information about their product lines, news, and job opportunities.

You can try looking for a list of manga studios, maybe on wikipedia. As for products, some of those "how to draw manga" books have recommendations on how to choose/order screen tones, copic markers/coloured ink, manga pens, etc (if that's what you mean).

I would highly recommend animemine.com100% for anyone who loves manga. AnimeMine is a new and exciting community social network dedicated to the anime, animation, manga, and the games we love. There you can discuss with other manga artists and you can get their opinions. We can create own distinctive identity, take part in forums and chats, make own blogs, and even upload personal videos and art.
Hope this is best site for all anime fans and artists.
Best of luck!
