Aligning widget

Hi!

I love this plugin because its the only one that gives me the option I need. There is one thing I don’t like. The aligning. I put the widgit on the bottom of my site but the aligning is gradually. I want to align the avatars horizontally next to each other with the names under the avatar. Have a look on my website [Link redacted] Any suggestions? Thanks for the reply and greeting from the Netherlands!
