A simple todo-list for a group
There are tons of todo-list applications out there, especially when it has become the extended helloworld for developers.
But what I miss is a simple online todo for an ad hoc group.
Say you and your neighbours decide on cleaning a patch for a football field and some tasks must be done. Get a proper lawn mower. Get a scythe. Ask Grumpy-old-man for possibility of leaving grass and small trees in his compost, get timber for goals, ask Bearded-with-pipe if he has an old fish net. Ask SO for coffee, lemonade and beer cooler. Decide time for next meeting.
Normally all these tasks are jotted down in text document (or gods-forbid msword) and sent back and forth to be spliced into 10 not correct versions.
Instead jot the tasks down on a web site. Get everyones @dress to make them accounts. (should be a click away, no more). Now everyone has access to said online document and can tick off tasks as soon as they are done. When a task is done – send an email to all others to show that stuff is happening.
This simple-todo can be extended with thousands of features but that might also make it harder to use so KISS.
I find that Google Keep (https://keep.google.com/) works well for this purpose: almost everyone has a Google account already and it is very easy to create and invite people to a checkbox note.
