Tired of writing your friend's dorky username that they picked before they had finished going through puberty? It's a lot easier to link to them with a custom name now. jai_dit can now show up as JD♥. <lj user="exampleusername" title="Your custom text goes here!"> (Note: it would be a wise idea to start hovering your mouse and checking where the link leads before clicking usernames, because some people have bizarre senses of humor.)
Pingbacks are here for paid users. (Note: there are still a few issues with getting that working.)
