I haven’t checked with our site owner, but a general rule of thumb would be not to share publicly any style files you don’t know FOR CERTAIN were not created by a commercial source. So, if you aren’t sure, you can’t upload publicly.

This is so the site doesn’t run the risk of being shut down for piracy. I am sure no one wants that!

If you aren’t sure, PM each other and share what you want to privately. Just be aware, sharing current commercially available styles cuts into the money the style creator makes, making it unlikely they’ll continue making them. And I’m sure no one wants that either…
