Kind of a wild card to appraise, and I'll just stick to the dot.com:
Sign Up isn't a specific enough item, service, etc. that hordes of people would naturally type in to search engines, like 'concert tickets' or 'car repairs', so the value won't be in natural traffic so much as in the popularity of the term, the branding value. It does have some good Overture, so you're gonna get some traffic income regardless;
But it's a killer name for branding. An extremely popular term, as pretty much any community- or service-based site nowadays wants people to 'sign up'. A great, great name for social sites, for how-to's about using the net, search engines, etc., for any legal/law site, for job or volunteer programs, even for sign makers or billboard companies that put 'signs up', ha ha. In short, anything to do with people and the internet could use this name for something!
I think you'll make a lot more $$ for this name in a lump sum from an end user, than you ever would from natural type-in traffic. Someone here might have a suggestion to counter that point, so welcome to any comments.
It's such a supremely catchy and common term, and so widely useful to a huge number of large companies, that big numbers should be involved.
Like I said, difficult to appraise, since it's exactly the kind of name where, if a few people/companies 'get it', see how neat it is, they could easily bid it into very high numbers.
Being sane and sober, I'd say:
resellers = in the low to med x,xxx range at least, maybe even high x,xxx.
end users = a wide, wide spread, based on so many factors; could be as low as 8 - 10K, or skyrocket to over 100K or more if the right people want it. Difficult to appraise with accuracy, but I'd say don't let it go for under 10, and better yet get it into some auctions and I think it'll climb much higher.
All this is, of course, IMlowerthantapewormpoopHO.
