Many times I have glanced upon an interesting topic but didn't have time to read it, and when I went back to sajha the thread was nowhere to be seen.
There's a solution for this now. If you see something interesting, you can save it for future reference. Once you save it, it will show up in your profile. There is also an option to make it private so that only you see what you save.
For someone who is not logged on this saving function will not work. However, if you are not logged on, I have put in the ability to send the thread to your email so you can come back and check it out later.
Hope these small changes make browsing sajha a better experience.
