I do wonder if it would not be helpful to users of this group for readers to be able to give "stars" or some other markers to posts that have proved particularly helpful. if these "Starred" posts were listed somewhere, together with their subject matter, viewers logging in may choose to study these rated postings.
For example, I have recently followed this post:
http://forum.enjoysudoku.com/viewtopic.php?t=410&postdays=0&postorder=asc&start=30
and feel a lot of people, ( as I did) would find Andrew, Animator et al's very helpful explanation of number groupings really useful.
