3 questions

Hiya!

First off, while writing a new post, how do you make a new line without skipping a row? I usually do it by pressing enter and shift at the same time however this also sends me to the top of the post which is quite inconvenient. Don´t know if the theme matters but I´m using twenty ten.

Secondly, how do you add friends? I don´t see a function for it on this site and I don´t have a function for it on my site 🙁

Thirdly, how long do you have to be active on this site in order for your name to link to your blog?
