Sign language differs from place to place. My main criticism: I'd prefer it as British Sign / American Sign etc. Regardless, hope you get a bid. If value does happen to be realised, I consider it Low XXX. If the other terms as mentioned (British Sign / American Sign), then I'd see it Low X,XXX. IMO
I think it is a hit or miss name. I suggest listing it on BrandBucket and putting a price tag in low XXXX or whatever they suggest. Long shot though. Worth 1 renewal.
