How to determine if multiple cells contain identical text but ignore the blanks?

I have data which identifies the initials of a user across a period of 5 weeks. See attached.
I need to identify if the same user was present for each row, but I have some weeks which are blank that I wan't ignored.
If I use the A2=B2=C2=D2=E2 simple formula, then the blanks will return a FALSE, when really it should return a TRUE.

I've searched through many more complex formulas but haven't found anything.
I'm assuming there's a simple solution I just don't see.
