Hi,

This might be an exreme FAQ but google didn't find anything useful so
here goes:

I'm yet another one looking for a usable ms-project like application for
Linux. So far all I found is MrProject, but it segfaults when reloading
its own saved data (without giving any information), and all
mailinglists about the projects (development, bugreports, users) are
apparantly nonexistent (just broken links on their webpage). Looks like
I bet on a dead horse here (and spent a few days of work on creating
unreadable project files).

So, are there any other alternatives I can try? All the functionality I
really need is to create tasks and subtasks, assign them to people, make
one task depend on another and display them in a Gantt diagram. Surely
this can't be difficult? :) Actually, apart from some fatal bugs,
MrProject looked like exactly what I need.

Or, is there any happy MrProject user who can tell me how he got round
the initial unusability of the program? :)

Thanks for any help,

Maurits.
