This is a great community for new bloggers. I read your post, and can 't wait to see more. I started following you on Facebook. As far as feedback, if possible I would make the header longer and shorter, and change the menu options to just below this. I couldn't find an email list, however I would suggest using one of two free services (they are free up to around 1,200 subscribers or so, which makes it great for us beginners). I heard great things about MailChimp, but personally I use Mad Mimi and like it very much. I also find great blogging advice in the book How to Blog for Profit, and from ProBlogger.com.
If you have any specifics, I can let you know what I have noticed so far. However, I have only been blogging since about October.
Good luck with your blog, it really is a nice way to find your voice.
