there is Private Plurk .. link is just above dashboard to the right

i mean to the left

"private plurks, languages & options" ... just start to type their plurk name in .. or even name I think

The problem with private plurks is that people don't see them unless they go to their private plurks page.

it's not readily apparent that there are new private plurks.

I have gotten privates and they show on my timeline?? Hmmm...

where is the private plurks page??

go down where it says friends and plurks. Click and private plurks only can be selected.
