Howdy. Peartrees has a bit of a learning curve. There are multiple ways to access and share just a pearl, a pearltree (subject area), a user (profile) and ask questions.
If you log into Pearltrees with a Facebook link, then whatever you do while working on pearls and trees gets posted on your FB timeline. If you want to be more selective, log into Pearltrees directly, and not click on use FB ID.
I prefer the second method (logging directly into PT).I have more control over what I want to share and what isn't ready for "primetime" yet. You still have the choice to post to your FB timeline.
Using the PT search will give you pearls and trees that have the key words in it. You can drag other pearls or trees to your tray at the bottom of the page > click the Home button in the upper left, and place the choices in your trees as you see fit.

@dolores: Thank you for New year Greetings. Hope for the best, prepare for the worst. We are definately living in a historical/pivotal period. I have been working for this since I was a teenager for the US to wake up. by Dec 31
