Thank you Tom, I don't think you can do it on your side.
I was thinking, as I spend some day time on my trading app, which is still under (slow) development, I could add a function to check if new posts arrived in topics I'm interested in without leaving trading page. If it would appear useful I could add a window to read the message right there or even to place an answer. I also could look at new posts ignoring side threads ("side" for me) while in trading hours, or do something else. As said, nothing to sweat on. I was just curious if there is API I can use, if not - Aeromir page is functional enough.
If I have nothing to do I may try do this using Aeromir's e-mail service... ;-)
