Mac User Group's online forum has a problem the webmaster is trying to resolve whilst travelling on holiday: no-one can upload to the site unless they're using a mobile device such as an iPhone or iPad.
At tonight's monthly committee meeting, I suggested selecting "Safari - iOS 9.3 - iPhone" as the User Agent under the Develop menu in Safari on a Mac to trick the website into accepting that the Mac was an iPhone.
The Group's Secretary (who uploads more than anyone else) tried that trick & reported to all present that it had worked.
So we have a work-around for the more geekish users. The others will just have to wait until the webmaster sorts the issue out.
