We have now set up a Bugzilla system for bug reporting/feature requests.
Please use this if possible as it reduces the risk of losing bug reports/feature requests.
To report a bug/request go to:
http://bugzilla.lysator.liu.se/enter_bug.cgi?product=Mattricks
To browse the list of bugs/requests:
http://bugzilla.lysator.liu.se/buglist.cgi?product=Mattricks&bug_status=...
This information is also available under "Contact" on the web page.
Enjoy!
