Ok, so let's revisit your original post:
If you don't appear, the court will probably enter a default judgment against you.
Rule 503(a) of the Colorado Small Claims Rules provides as follows: "All actions in the small claims court shall be brought in the county in which at the time of filing of the claim any of the defendants resides, or is regularly employed, or has an office for the transaction of business, or is a student at an institution of higher education." Rule 503(b) provides as follows: "If a defendant appears and defends a small claims action on the merits at trial, the defendant agrees to the place of trial."
If I understand your original post correctly, you do not reside (or do any of the other things) in Jefferson County). Therefore, you may be able to object to the venue. Is it worth doing that? That's for you to decide, but my guess is that it probably isn't -- especially since you have designated the address where you were served as your mailing address, which any concerned person is going to assume means you live there.
That leaves the question of whether service on your daughter was good service. Under Rule 504 and Rule 304 of the Colorado Rules of County Court Civil Procedure (which I don't have a link for), it is not, but only because you don't live with your daughter. However, as noted above, you have created a situation whereby folks can reasonably assume you live there. It is worth filing a motion to quash service? Again, that's for you to decide, but I would say no. You'll eventually get served properly, so why not just proceed to having the case decided on the merits?
Informed by whom? You can, of course, send whatever e-mail or other correspondence you want. However, I can assure you that folks in the business of collecting debts do not give one iota of concern about someone saying, "I will attempt to file bankruptcy." Filing bankruptcy will put a halt to collection proceedings, so if you're going to file bankruptcy, just do it. However, as "army judge" noted, it may be that you have no non-exempt assets such that any judgment against you could not be collected. That's something to discuss with a local attorney if you're inclined to explore the bankruptcy option.
