Sorting by Bold V. Normal Font

Hi,
I have a ton of lists to sort. Column A is the name of the person and column B is his/her email address. There are hundreds of rows filled with names & emails. Anyone who attended a certain event is listed in Bold (both name and email address). The people who didn't go to the event is written in a normal font (not in bold). I need to put all the people who attended the event (Bolded people and their emails) on the top of the page and the people who did not attend the event (non-bolded people and their email) at the bottom of the excel. How can I quickly do this? Thank you!

Also, can you give really clear directions when you answer this (like an answer for a beginner to Excel) - I am totally bad when it comes to the function formulas....

HI,
Actually this just seems to identify the bolded names as True. I am trying to move all of the bold names to A2, A3, A4, etc - the top of the document, and all the non-bolded names to the bottom of the excel file. Please help. thanks so much! G
