Hey there, Sarah!
I'm friends with Melissa here on TH, so I thought I'd drop by and say hi since she told me you were here. I'm Hollie, and I'm a buddy just like her, so if you have any questions you'd like to ask me, you're more than welcome to do so.
Just like Melissa said, the site is a really nice place. It's really friendly and people here will make sure they make you feel welcome, so don't worry too much. You're lucky you know someone on here to help you out, especially someone like Melissa, she's not only staff, but she's awesome.
Let me know if I can help, yeah?
Take care!
