Re: [ALUG] Todo/Task 'links', does any program do this already?

This sounds very much like Google Notebook, with the firefox extension, to me. It's no longer being developed, but I believe the service/extension might still exist. Failing that, I believe zoho notebook does the same sort of thing, but I haven't used that. These are not tickable task lists per se, but like other web utilities, can probably be used as such as long as you have that prompt.
