Advice on the uses for the Tick it Plugin

I am writing to ask if anyone thinks/knows whether or not I can use this plugin in the way that I'd like to use it.

I am trying to turn my simple wordpress into a MU site. I'm doing this so that people can sign up any have their own websites on my site.

With the signup, I was going to give them a free wedding checklist. Currently, it's in a printable format. BUT, I was hoping I could create it with this plugin and have it be part of every person's sign up. I would like it if they can add and take away items as they wish.

Anyone know?

Any advice/opinions appreciated. I've bought a lot of plugins that didn't end up doing what I expected so hope I don't make that mistake again.
