your question was posted anonmously because you haven't created an account or you weren't logged in. if you create an account and login your posts will show up under your name like this post is by zengargoyle. you also get a spiffy homenode where you can put things if you like. having an account also lets the rest of us know how long you've been around and once you've posted a bit let's us know a bit about how you use Perl and how we can best answer your questions.
until you do create an account and log in, all of your posts will be Anonymous, some monks here think that allowing anonymous posts anywhere anytime (how it works now) is a good thing, some think that anonymous questions are ok, but anonymous replies aren't (you don't know you can trust Anonymous to give a good answer), some want to make everybody create an account before posting but think too many newbies wouldn't want to and would leave instead of creating an account.
that's what this tread is mostly about.
i'm pretty sure that most of us would like you to create an account if you find perlmonks a usefull place you like to visit so we can maybe get to know you a bit better. but you're free to remain Anonymous if you like.
