Dear friends: if you use Dropbox, which is a a fabulous free cloud storage service, you may want to pay attention. Today is the first day to opt out of their new term. They are beginning to assume all users agree to a clause that requires they submit all claims to arbitration, unless you opt out during this short (30 day) period.
The third paragraph talks about "Opt-out of Agreement to Arbitrate," and gives you a simple hyperlink to click on to do so. You only have to fill in your name as registered with Dropbox to complete the process.
You can read the plain English terms they have there explaining their arbitration agreement. It makes it sound nice and friendly and very attractive. You might note, however, that you are also agreeing that you may not bring any class action, and that if the arbitration fails, you have to bring your suit in San Francisco, California, unless it's a small claims action.
The reason I am opting out of arbitration without a second thought is an article written by my colleagues here at Suffolk about shrink-wrap and click arbitration clauses. These assume you have agreed to binding arbitration to solve disagreements with online service providers, software developers, etc., by unwrapping your package or by subscribing to the service. Dropbox's terms are not too abusive, compared with some of the agreements discussed in my colleagues' article, but it was enough to make me think very hard about agreeing to any sort of forced arbitration clause!
