Pinterest Questions

While I'm no stranger to browsing Pinterest, I haven't joined yet. I'm curious about a couple things:

1. Is there a way to go to the holiday category and only pull up Christmas? Or the crafts category and only pull up crochet? Do you need to join to be able to do that?
2. Why is it almost impossible to be able to find a link to the recipes? I find that I have to click back through so many other pins of the same thing that I eventually just give up, am I missing something?
3. Are there any suggestions or tips you'd like to share with someone that's thinking about joining?

Thanks and have a happy day:@)
