Avatar Size Increase

I feel like a 30% to 50% size increase would be a good idea.
They seem small. I've tried several shapes and resolutions and always am disappointed in how the images are displayed. They don't feel like they st well within the postbit to me. They line up nicely with the titles and user names but I still feel they should be larger.

I'll up regular member avatars to 150x150 and premium user avatars to 200x200 and see how that works out.
