For my group, all I need is a file drop for the monthly calendar. PDF is fine, as is text.

I noticed that a Thunderbird pdf when read on a mac with preview, will find the dates and offer to add them to a calendar. It didn't have permissions to export other formats (?????) I gave it permissions, but the pdf worked. Text and pdf are good. People were struggling to populate Word calendar templates, a great waste of space and impossible to read on a small screen.

The catch is that the URL should be updateable with the latest pdf as events trickle in. Fixed, so people can bookmark it!

Can this be done?

Expiration of one month is fine, and while a fixed "forever" url is nice, one that's stable for a month is ok. It just needs to be reloadable with new pdf's for the month. I haven't seen this with free file sharing sites

It's just that users are not computer geeks, and the fewer changes they have to deal with, the better.

Author protection is good. Security by obscurity may be ok for users, although unwelcome guests might warrang a password.

Sharing a small file usually turns into creating folders, setting permissions, and hoping the recipient can access it.

This approach keeps it simple:

Upload a file

Get a link

Share and download

Extras that matter for quick sharing:

Link expiry

Password protection

No account required for the receiver
