Have anyone tried ANY of the alternative to nodecomments for D7?
For me it seems, that Reply it is partial match for this module.

p.s. I am sorry for writing it in this queue, but there are NO real substitute for this module in D7. My task is very simple: make an OG/forum website with posts as nodes and replies as nodes also, as all the subsequent building of the site is simpler by the factor of 10.
