Hi & welcome, there is loads of info on here. As Silver says there are all the different bits of the forum with lots of advice & especially usful things are stickies at the top of each forum page. There is also the wiki with advice on taming etc. Have a good look through & then maybe post again if you have any specific questions after that.
Good luck & enjoy all the reading, there's loads to learn about hamsters & lots of fun stuff you can do to make your hamster's life with you really good
