The fork is due really soon.
What is the ETA on the fork?
if we're running .6.72 client are we OK?
.72 should be fine. Afaik .73 was only a bugfix.
I think last I heard was feb 1st for the fork. Better to check the block count and wait for 440k as that's what it actually depends on not a specific date or time.
correct. 0.72 was a minor update for bugs and is fine if the bugs aren't bothering you.
