You can create as many task lists as you like, but you're right in the sense that you'll have to remember each URL you create. I have a dashboard feature in development to organise task lists you've viewed/edited/created, and I'm currently deciding whether or not that should be a paid feature.
I've changed the footer as per your advice.
That's fair enough, I understand that for generic use there are better free apps out there to use. I'm really trying to appeal to quite a specific use case, which I believe is quite common in multi-office environments. It may be quite ironic that I still use RTM in parallel for task management, as I myself do not fit in the target market for my own product!
I do know of some business who already happily pay for services like this, but you and I probably wouldn't find it as valuable.
Thanks again.
