To the best of my knowledge, only Mozilla Firefox works. Platform issues are still being worked through.
I seem to be having trouble making the signs appear after I drag and drop them
into the editing box area while using Google Chrome. It works fine on Mozilla
Firefox, so perhaps this is just an issue my browser hasn't worked out yet.
(My initial inquiry was about deleting an erroneous entry, but I believe that was
fixed by simply logging back in.) Many thanks!
