Yes, there will be a NetCourse, and I hope we'll have it ready late in 
the year.

In addition, I have agreed to write a column about Mata for the Stata Journal.
The first of those in columns will appear in the next issue and is on
translating Fortran into Mata.  I am very pleased with the first column.

I'm thinking about making the second on data management and Mata.

I can think of a few data-management problems, the solutions for which we
programmed in Stata, that if I were writing them today, I'd write in 
Mata.  -cross- and -fillin- come to mind.  In addition, Mata would be the
natural language to implement -outreg- and its decendents.

That said, most data-management tasks involve sorting and merging, and 
Stata is data-management language, and the better choice for most
