It would be great if there was more automation in linking existing users to their other profiles on StackExchange.

For example, this user on Area 51 is this user on StackOverflow, but his reputation isn't showing. Likewise

  1. this guy is this guy,
  2. this guy is this guy
  3. this guy is this guy

and maybe some others just in the Mathematica proposal alone.

Meanwhile this user has inadvertently managed to commit twice, because he previously committed as an unregistered user.

A simple fix would surely be that users had to register to commit (but could follow as uncommitted users). That way, it would be more likely that the user's reputation on other sites would actually be recorded and count towards commitment scores.

Another useful response would be to match against email addresses and merge accounts more automatically. I do not know of anyone who wanted to keep their Area 51 involvement separate from their StackExchange profile, and yet used the same email address for both.

I know this has come up before, more than once in fact, but I don't think this is a dupe of those questions, because it is different users this time.

Proposal: Mathematica

Paul only has one rep on SO, so the link is pretty much irrelevant, and balboa has already associated his account. I understand that there could be errors, and that digging these up is tedious without additional information, but you might consider removing those. – Kevin Vermeer Jan 6 '12 at 18:23
I think the associations might come in over time. The lag of noticing that someone has gained 200+ rep on another site since committing is also pretty substantial. – Verbeia Jan 6 '12 at 19:56
Meanwhile, this unregistered Area 51 guy is this StackOverflow guy. – Verbeia Jan 9 '12 at 20:02
Thanks Verbeia for being so thorough and showing us the light. This unregistered Area 51 guy is now registered :) – István Zachar Jan 12 '12 at 10:56
@IstvánZachar you are welcome :) – Verbeia Jan 12 '12 at 11:09
Your solution is clear and should be activated sheila leahy – sheila leahy Mar 12 '13 at 22:12
lf the change you suggest could be put into effect, the site overall would be more effective and open. sheila leahy – sheila leahy Mar 12 '13 at 22:15
The automatic process can definitely be improved, especially on Area51. Note that "you can just flag one of the posts by either account and leave us a message" (and, if not applicable, possibly flag the proposal itself and reference both users in the message). And yes, there are a few cases of this, but not sure if it's actually a big problem. Even if it's 10% of all commits (which seems high to me), that's still 90% legitimate commits. And if the user has a massive amount of reputation, he/she will probably know how to commit correctly. – Dukeling May 11 '13 at 15:26
I also commit twice by mistake. The feature of being able to commit without registration should be removed. I also have no clue whether the rep from Area 51 will be added to stackoverflow(I have some rep there). – Mythic Cocoa Jun 21 '16 at 12:05
