Over the past few weeks, I've been mulling over how 247Toolset will do reminders. What are the expectations of the admins? Their audience? How will they use it?
After a lot of consideration, I determined to blend it with another feature I've had on the plate for some time, which is to create our own version of bit.ly. Toward that end, I created 247.ms. And it works great - if you go to http://247.ms/brett, for example, it will take you to this blog. Each time it's clicked, it increments the visitor count in the database so that we can tell how many times it was clicked. (It's not purely a bit.ly app, though, in that it doesn't allow people outside the network to create shortened URL's... it's just for 247Toolset's links internally.)
A reminder is sometimes sent by email and sometimes by text message. This is why the short URL is important.
This effort opened the door to another function we'll be releasing, which allows for text messaging to sign up or donate - or other things.
You only get to new places by exploring. Exploring is fun :)
