Any Advice?

I'm going to switch our template (finally) from Old Blogger to New Blogger.

Based on your experience, do you have any suggestions or warnings? Or will it be easy and trauma free?!? (What big change ever is?!?!)

While I'm asking for advice and suggestions...I'm back at the beginning of a loop and thinking about how I will introduce myself and my classroom to a new set of parents and students. Those of you who do that every year (I'm a 2-year looping teacher, so it's every other year for me), what kinds of things do you do to introduce yourself and your classroom before school starts, in the first weeks, and at your Curriculum Night/Parent Information Night?
