Call off the Cavalry Terry
A friend solved it for me. llana77, liana77 and ilana77, are three different people!
MY list showed the member as the first name.........I tried the second name as "ll" only usually used by Welsh.......the person I was trying to remove used the THIRD version. Tried that........Bingo........removed! Sorry for the confusion, but I was baffled!
Quite how the "List Team Members" option had cottoned onto the wrong name, remains a mystery, however it did !! Meanwhile problems solved and just remains to say that, "The Team Leader of Triviabiz apologises for inconvenience caused"
