It's the same length, so either way works and I'm pretty sure people understand where to get them regardless.
Some other suggestions (and maybe we should have a Sticky FAQ for the inevitable Xmas newbies* so they know which stores carry formats compatible with their shiny gift/sale readers and what "DRM-free" and "MultiFormat" mean and that the freebies tend to expire pretty quickly so they shouldn't wait to grab them):
- All Romance eBooks: AREbooks or just ARE if AllRomance turns out to be too long
- Barnes & Noble: to B&N obviously, if it turns out that extra letter in "nook" is really squeezing matters
- Christian Book: ChristianBk or XtianBook, perhaps
- Ellora's Cave: Ellora or ECave, depending on how much space there is
- Fictionwise: FWise or FW in case we get a rare freebie there (it turns out they have some of the Harlequin promo stuff, if anyone really wants a Secure eReader version of that holiday anthology)
- Harlequin: HQN (they actually call one of their imprints that)
* Apparently the most readers the forum ever got online at the same time was on Christmas day last year.
