May seem a little silly, but here is an analogy for you.
Suppose you are an employer and you have a meteorology job open. Then suppose your only requirements for an interview are just to show up, no filling out an application or anything. The employer will have all kinds of people show up, including some that have no business even being there. Now the employer will have to scramble with tons of interviews to get to the right candidate that deserves the job.
Now, suppose the employer states in the job opening that the possible candidate must talk into an answering machine and tell the employer why he/she is the right candidate for the job. Then after the employee listens to the messages, he/she will know who the prime candidates are and can then interview them personally. Of course the candidates can lie, but the employer will still have a good idea who is fit for the job and who isn't.
So, as it pertains to this, we don't want everyone and their dog to show up and sign on to Stormtrack. We would rather have fewer, more serious and dedicated candidates show up and add value to the forum.
As the poll shows, most people here would agree.
