The trial experience has the following features:
1. The speed of the Free account is average;
2. Simple operation, intuitive interface, and the page design looks decent;
3. Not many functions, and poor support for external services (for example: Blog This currently only supports Blogger);
4. You can upgrade via accumulating points, but if you want to achieve a permanently free Pro account, it might be quite difficult;
5. No file privacy settings (it may not be very useful for them, but I feel like it should be there);
6. You can import your Yahoo, Hotmail, and Gmail contacts to share pictures, which is quite practical.
