I imagine you're quite right. I am unconcerned, however, because I am planning this for a niche group, and the average requests might be fewer than two per day (it might go a week or more between "bursts" of activity, and likely will have only a handful of individuals even accessing the site--fewer than 20, to be sure).

Now, once put online could it go "viral"? Perhaps. In such a case I would probably have to put it behind a login. But I really do not expect to have much trouble with traffic, at least not for some time.
