Meta Stack Exchange is where users like you discuss bugs, features, and support issues that affect the software powering all 157 Stack Exchange communities.

What is meta?
Here's how it works:
  1. Any Stack Exchange user can ask a question
  2. The community provides support, votes on ideas, and reports bugs
  3. Your voice helps shape the way Stack Exchange operates

Background: when question is migrated from site A to site B and the author doesn't have account in site B, he will appear "gray" until he logs in to site B and associate the accounts, then the avatar show and all is good. No problems here, same for answers and their authors.

Problem: if user from site A posted comments while the question was still in site A, his name will stay gray and unclickable even after he logs in and have account in site B:


This is the above question, but most likely it's global problem, not specific to that one occurrence.

Nick already answered this elsewhere on meta, but basically comments don't contain enough user information for us to reliably map them in all situations. – Jeff Atwood Feb 21 '12 at 9:18
@Jeff thanks, didn't see such answer. Isn't there user ID associated with each comment? Just the raw display name? – Shadow Wizard Feb 21 '12 at 9:23
@Haney since you added the deferred tag, any updates about this? – Shadow Wizard Apr 28 at 9:15
@ShadowWizard none at this time. It's not critical and we're slammed at the moment, but one day we hope to investigate further. :) – Haney Apr 28 at 15:58
@Haney thanks for the honest response! – Shadow Wizard Apr 28 at 17:57
@ShadowWizard all I can be really. – Haney Apr 28 at 18:08

Here's the answer Jeff's referring to on why this doesn't happen currently:
Comments by OP on migrated question become "anonymous"

We may revisit hooking up comments in the future, but it's not a completely trivial problem (e.g. should reply to hook up as well? that's more info that needs carrying over), and won't/can't be retroactive. That being said, I do have an idea on how to take care of this in a not terribly expensive way, I'll throw it out to the team and see if it's worth it.

Cheers, good luck with that idea of yours - hope it will be accepted and implemented. :) – Shadow Wizard Feb 21 '12 at 11:13
At the very least, could commenters be notified in some non-expensive way that the question is being or has been migrated? – Aaron Bertrand Nov 12 '13 at 21:27
Three years later, any update? – Shadow Wizard May 28 '15 at 21:00
