Jen, click the plurk. It will open up a drop down window where you can type your answer down at the bottom.

I don't think they know they can click on a plurk and follow the conversation

You can use the "@" symbol same as on Twitter to link to another person.

You'll get it soon enough. Just get ready to get dizzy chasing threads.

Jenn, you can also click on the "is" bit on the left and change the word for each plurk (or use no word at all, as I do)

Twitter would fix itself

now you're getting the hang of it, JenniferyLaycock!

Now, if I could just spell your name, we'd really be cooking with gas...
