Ok, with regards to using usernames, you can use the xml from post 32 to have it setup that way -

With regards to the line break, go into your templates - postbit_social1 - find <br /> and remove it, save and that's you.
It's stupid, i should never have used a line break as not everyone was going to use all of the options. So in the update i have implemented a wrapper.
