As most of you already know; SXC has more than twice the traffic as StockXpert has, and SXC has also a feature that allows you to promote your StockXpert portfolio from your SXC portfolio by putting a banner on your profile page!
But now I have find a way to promote your StockXpert portfolio even more, and I wanted to share this with you.
Why am I sharing this secret with you, you may ask!
Well simple; the more SXC downloaders head over to StockXpert, the more traffic StockXpert gets, and I will benefit from that as well! 
Here's the tip:
Put a good quality image on SXC and integrate in some way your StockXpert work in it, so you can put a link to your StockXpert portfolio in the description of that image!
My guess is that people read descriptions more often than that they read someone's profile!
Besides, I think the StockXpert banner on the profile page is not very obvious and can be easily overlooked!
Here's mine to give you an idea:

LOL, did you have a property release for that hotel room?

No, that's why I uploaded it to SXC, all the paid stock sited rejected that image for exact that reason! LOL
