How to place a specific comment on top of list PLease help me with this requirement in D6.

I need to mark one comment as best, so this comment should stick on top of all comments posted irrespective of sort order.

How can this be achieved, any ideas?
Found Best Reply module.


  Best reply module allows node authors to mark a particular comment as the best reply. It aims to encourage quality comments and to give some recognition to people posting quality responses.
