I just released a large update to Bumperdo. It has been in the works for quite some time, and brings a couple of new features that were lacking, such as allowing you to change your profile and password, upload an avatar, there is a more useful start page where deadlined tasks are already shown, and there is a new (basic) activity page.
This update lays the groundwork for more extensive updates in the future: I was running into some walls regarding legacy code etcetera.
It might, due to the large amount of changes, very well be that some things are broken. Let me know at firstname.lastname@example.org and I will try to fix them as soon as possible.
Thanks for using Bumperdo!
