Mantis
To report not only bugs but also typos and suggesting ideas (in a way they will stick), you need create an account to Mantis.
Mantis can be found from here:
http://naga.icesus.org/mantis
Create an user to Mantis with the same name as your Icesus character (e.g. if my Icesus character's name is Cyto, I create an account named 'cyto' to Mantis).
Once your Mantis user is created, then paste this the line below to Icesus:
accounts I want my Mantis account activated.
Once you get a positive reply, your account is active.
Below is described how to create a bug report, a typo report and a idea report in a way that it has the best chances of getting done.
All report types below require you to login to Mantis first.
