This has been discussed before.
Here's one thread from a couple of years ago. I am not privvy to why this didn't eventuate.
Does the following "devil's advocate" argument have enough merit to counter any of the "for" arguments?
Much of the board's use is by members and non-members searching out existing answers, not asking their own question.
Take this example. Somebody (using Excel 2010) today seaches for how to count with multiple conditions. They find a thread I answered last year and the OP's profile says Excel 2010, as does my profile. My answer says, you'll have to use SUMPRODUCT and you cannot use whole column references.
Does the searcher go away with the best information to solve their problem?
Do they think I am an idiot?
They have no way of knowing that when the question was posted and answered that the OP's profile (& possibly mine) said Excel 2003.
Now if the versions are not shown in the profile, the searcher is still going to find the exact same question and answer. But could they be less swayed to thinking this is the best answer for them?
