A lot of us use both.
Aside from the VCR, and the capture/working resolutions, there tends to be very little difference between PAL and NTSC (and SECAM). Only the goofy formats like PAL-60 ever pose a problem, and that's only used in Brazil, and for PAL hardware that cheats to "convert" (not convert) a signal.
I often mention x576 (PAL) and x480 (NTSC) in my posts and guides, for this very reason. At any time, I may be posting samples from either format.
There are additional profile fields aside from location, but nobody ever uses them (and I'm guilty of this myself). At one point they were customized, not forum software default. But again, nobody used them.
A location of "NTSC + PAL" would suffice, to keep it short.
Are you running into any particular problems? Feel free to always ask in post reply, to help clarify.
