I'm on both TrendMe and Olioboard. There are pros and cons to both. I think TrendMe is better for the artists in us, but it's much easier to import items on Olioboard, and you can crop items, which you cannot do on TrendMe, at least I don't think you can crop here. Here's my Olioboard link, if you care to check it out:

On TrendMe, it's so confusing to me how to name and list what category your item goes into. Olioboard is more like Polyvore, in that you just import it without all the different options; and they have a clipping tool to put in your browser. Unfortunately, I haven't yet figured out how to get it to work! But my best Pro for TrendMe is that most of our polyvore friends are here!
SO WHICH DO YOU LIKE BEST TRENDME OR OLIOBOARD? I COULD NOT FIND A THING ON THERE TO DO ART SETS THE LAST TIME I WENT THERE I WILL CHECK IT OUT MORE SOON...THIS IS FANTASTIC MY FRIEND...LET ME KNOW WHICH ONE YOU PREFER♥
