Since many years now I use GTG to manage my todo lists. (it can even be <a href="https://addons.mozilla.org/en-US/firefox/addon/gtg-task-button/"integrated in firefox).
I tried to use Remember The Milk service to sync my laptop and my desktop but it wasn’t really working well. Then I discovered a nice project : GTGonline, a Django project that allows the synchronization to and from GTG via a backend called backend_gtgonline.
I forked the project to create a branch (that will never be merged it seems) to not hardcode the
url of the service as I host my own version of GTGonline backend.
My branch is https://github.com/lefred/backend_gtgonline/tree/service-url and I also provide a rpm package for Ferdora 20.
