JF
It makes more sense if you put JSFfan on your ignore list. He's a troll - a sort of inverse Tribble who thrives on being abused.
There are about 20 pro-JSF trolls (some with multiple identities, including JSFfan). They're not interested in anything except vandalizing discussion threads where the program's many and serious challenges with cost and schedule are being aired.
Luckily we have only one of them here. Until the Mods squash him - jam on!
