And Hi again,

I found it! On page 90 the book says:

<quote>
... (Well, almost. Extensions must be shorter than 80 characters long,
and you shouldn’t use single-character extensions for your own
use, as they’re reserved.) ...
</quote>

O.k. - This answers my first question ("if there is disadvantage if we
use only 1 digit extensions").
But what for are single-character extensions "reserved" ?

Thanks,
Norbert
