Hi. Just thought I'd throw my thoughts in for good measure... I see where you going with T1DY but I just have two small concerns. First is the pronunciation. To me it reads "T1 die". I'm sure this isn't what you're after, but I think it's important to think about how the name might sound and as well as look. The other thing that I think you need to consider is why teens and young adults will want to join such a group. When i was a teenager I barely wanted to admit I had diabetes, never mind talk about it. I'm sure I wasn't the only one! Think about what you're offering your potential audience. If I'm a young T1 why should I join this group? What's in it for me?
Sorry, I'm not trying to criticise your ideas, althoughnit probably sounds like it! I think you're onto a really good idea with this support group. I just think you needn't put a but more thought into how you position it. Happy to talk more about it if it would help. Feel free to PM me if easier.
