I commented on someone else's answer on SO.

Then the post was moved to SF, where I don't have the required rep to comment other people's posts.

The answer poster @commented me, but now I'm unable to reply.

IMHO you should be always able to add comments to any post or answer where you do already have comments, regardless of reputation.


Go to your profile page on SF, click "accounts", unassociate your accounts and reassociate them. I suppose you didn't have 200 rep on SO when you first associated the accounts. Now that you have enough on SO, associating with that will give you a 100 rep bonus on Server Fault. Then you can comment.

    as long as you have 200 rep AT THE TIME OF ASSOCIATION you will get the 100 rep bonus on the target site. – Jeff Atwood May 6 '10 at 9:31
