That name is never explained in the document itself, but the top result I get for a search on "JAMS INC arbitration" is this arbitration company. Is that the JAMS to which the ToS refers? (I can't imagine the answer is "no", but I just want to be clear.)
And of greater interest, how/why did the company choose JAMS rather than, say, the American Arbitration Association (an organization mentioned in the Terms as a backup option) or another competitor? I'm not endorsing or complaining about anyone here, I simply want to understand the thought process. And I want to give the company every opportunity to put itself in a better light before I make a final decision on how I feel about this.
