Choosed threads on index

[martin1]

I'm looking for a hack which could allow me to specifiy few threads I think they are important to my visitors , and after choosing them, to appear on the forum index sidebar.

So it's something very similiar as built in option in admincp forums&moderators->forum block manager
forum threads , but there is no built in option for choosing specific threads, only by some term as most viewed, most replied etc.
