[Courses] [Tools] Delay in final lessons

[Mary]

Hi everyone,

Since the final lessons are taking some time to prepare, I'm going to
be posting them every fortnight rather than every week. I'm also
deleting "an introduction to version control 3: distributed version
control" since its content has been moved to other lessons.

An amended schedule is at
http://www.linuxchix.org/content/courses/tools/ and the next lesson will
now be posted Nov 5.
