The popup shows the changes to your user name (currently Kjuly).

From the dates, it appears to have been an Anonymous account that then got a GUID followed by your current user name. Possibly this is from an automated migration from another account.

See this question and links from it.

@Kjuly - As I said, this may be a result of an automated migration. – Oded Dec 24 '11 at 17:06

@Kjuly: No, only you and moderators can see your recent names. – Tim Cooper Dec 24 '11 at 17:14

The odd GUID-like account might have been caused by linking accounts; see Linking / creating account on other sites adds 2 “recent names” to your profile?, @Kjuly. – Arjan Jan 7 '12 at 20:04
    
Thanks @Arjan ! :D – Kjuly Jan 8 '12 at 4:10

I think this is what the recent names in your case means:

  • When you first visited this site you were an Anonymous user.
  • Then you tried to log-in into the site and the 2nd string is probably the unique identifier from the service you are registering/loggin in with.
  • After these steps you got your current username.

Hence, you have got 2 other display names in the recent names list.

Ya, I think so, but I wonder why it didn't show until yesterday. Anyway, thank you for your reply. :D – Kjuly Dec 25 '11 at 4:07
