Glad to see you there John.

OK, well, for a start - yes the Mandrake install should have setup swap
itself.  However, it may have just made it's own swap partition rather than
using the one you defined, although I doubt this, most installation routines
are fairly clever about that sort of thing these days.

Anyhow, to answer your questions:

1. Linux doesn't _need_ swap, but it's good to have.  With 768MB of physical
ram you may find that Linux never uses its swap space.  Even so, I would
suggest that you have at least a few hundred MB of swap set up, just incase.

2. If you suspect that you don't have your swap space in use then doing the
following will bring it online:

su -
swapon /dev/hda3

... remebering to replace /dev/hda3 with the device name of the partition in
question.

3. A good way of telling if your using much swap space is to run a
monitoring tool.  `top` is the classic commandline tool for this sort of
thing, but to make your life less confusing I'd suggest hunting down the
graphical app grekllm.
