Hi Itsy Bitsy and welcome to WriteWords
You have a choice of full membership or the cheaper part membership.
If you want access to, eg, the Writing Jobs and Agents Directory then it might be worth paying for Full membership. If, however, it's the writing forums and the private members and lounge forums, you're most interested in - for posting your work for feedback, and to hear all the gossip - then part membership (Community Only) may be more use to you.
You can always upgrade your membership at any time if you join on part membership and then decide you want access to all the WW facilities.
Personally, I started off on a one months free trial then, since I only wrote for fun, chose the Community only package. Now I'm at the stage of submitting my work to agents and writing competitions, etc, then I'm finding full membership is proving useful to me.
If you have any other questions feel free to ask.

<Added>If you are serious about your writing, then WW is one of the best for advice and experience.
If, however, you are just starting out and looking for somewhere to meet other new writers, then it might be worth checking out some of the other (free) writers forums first.
