I'm logging in using the OpenID from http://openid.stackexchange.com and using Chrome 31.0.1650.57 m if that matters.
Steps to reproduce:
DECLARE @MyUserID INT = ##UserID:int## SELECT TOP 1 Id AS [Post Link], Score AS [Score], CreationDate AS [Creation Date] FROM Posts WHERE OwnerUserId = @MyUserID AND PostTypeId IN (2, 3) ORDER BY CreationDate DESC
Then press the Run Query button and see if the UserID field is filled with your own user ID like shown in the below screenshot:
Did something changed on the
##UserID## parameter (e.g. that it's not supported anymore) ?
- if so, then there is an outdated help paragraph about it (What's the point of logging in)
- if not, it is a bug which is there about 3 days (I've been waiting since I noticed that you were going to do some changes to Data Explorer, but it remains there, hence my question)
