Glad you like the forum, hope you learn a lot before adopting your new hamster
If possible, try to adopt from a reputable breeder or animal rescue before purchasing from a pet store. Buying from pet stores supports animal sales and commercial breeding, which isn't good for the animals! I've bought from pet stores in the past, when I was a little kid. As an adult, I learned better and adopted from a breeder and the experience was totally different.
With that said, I look forward to seeing pictures and hearing stories about your new hamster(s)!
