How to find the right user name to address him or her with @

Hi,

I often find it hard to address the author of a post with @... Sometimes, as in the post below, the displayed user name seems to contain no cue concerning the real user name:

https://community.sdl.com/product-groups/translationproductivity/f/studio/30462/xlf-file-generated-by-transifex-not-recognized-as-a-translatable-file-in-a-studio-2017-project

At other times I am offered a list of user names like "Joe Doe_1234" "Joe_Doe" "Joe_Doe_2348" and so on, but I have no clue which Joe DOe is the author of the post. It would be helpful if mousing over the displayed user name would reveal this.

Or maybe there is a way, but I did not find it yet...

Thank you

Daniel
