I am interested in being able to host a spreadsheet for all of my potential clients who are Mac users, I want them to be able to use the file and have it work the way it does in Excel 2010 on a PC. The spreadsheet is heavily dependent on a custom ribbon and VBA.
There will be a small number to start with (5 or 6), but this may rise to hundreds.
Does anyone have any recommendations for a reasonably priced way of achieving this. The prices I've been quoted so far are prohibitive (in the region of £50 - or $85 -  for three months for EACH user, then rising after that).
Any pointers gratefully received.
Thanks
M
