Center avatar & add break

[Lynne]

You have this:

.postbitlegacy .userinfo .postuseravatar, .eventbit .userinfo .eventuseravatar {    clear: both;    display: block;    float: left;    margin: 3.33333px auto 0;    text-align: left;    width: auto;}

You need to add some css to text-align: center and float:none. Also, add some padding-bottom to your .usercenter class.
