Hi, Lisa, and welcome to WriteWords.
It's best to join one of the Groups first, and then you can upload an extract of oyur work into the Group.
you'll find the list here:
http://www.writewords.org.uk/groups/
New members tend to congregate in the Beginners Group, although there are active genre groups, such as Womans Fiction and Childrens Fiction, depending on what sort of thing you like to write.
As a trial member you can join one group and upload one piece of work.
To upload a piece of work click on your 'My WriteWords' in the top right hand corner of the page, and oyu'll see 'Click here to upload new work'. On Step 2, half way down the page, oyu'll see 'Which Group?' next to which should be the Group oyu've chosen to join. Click in the dot in front of it to select that Group for oyur work to upload into, otherwise it'll go into the Archive where it's liable to be overlooked. If you don't see a group listed next to Which Group then your application is still pending and oyu'll need to wait a few hours and try again.
You can introduce yourself by posting a thread in the Topic section of the Group you decide to join.
If you need any help, just give us a shout.
