That is sweet Max! Can I use my Cambridge GPS 20?

Of course, you can use any logger you want! SkyLines does not
validate the IGC files. We want to push technology, but we don't want
to stimulate the logger market.

There may be "real" contests hosted by SkyLines in the future (which
we encourage and support), and these may require a valid G-record.
Scientific projects may decide to filter invalid IGC files out.

SkyLines is designed to be free of barriers, and arbitrarily asking
people to buy new expensive loggers is not what I will do. Everybody
is free to decide whether he will trust an unsigned IGC file or not.
That's not up to us to decide.
