Hi Candiflare, good to see you're taking thep lunge
You'll find the Groups listed on one of the orange tabs above.
And, for convenience, here:
http://www.writewords.org.uk/groups/
Click on any of the groups and oyu'll see 'Click here to join this group' on the Group Homepage. There will be a pending period of a few hours while Admin. adds your name to the Group.there is a Journalism group, but it's not very active. For feedback it's best to join an active group. Most are Fiction and Poetry, but you might consider uploading in Beginners or even Short Story.
As a Full Member oyu can join more than one group, and can move around groups until you find one you're comfortable in.
Alternatively oyu could just upload in the Archive, but work tends to be overlooked there.
To upload a piece of work click on your 'My WriteWords', top right hand corner of the page, and half way down the pae you'll see a 'click here to upload new work', and follow the steps. If you've joined any of the groups you'll see a group (or list of groups) at the bottom of the page in Step 2 to choose to upload your work into. If you don't choose one, or if oyu haven't joined any groups (or if you're still in the pending period) then the work will go into the Archive.
You will see an 'Owner Edit' facility on any uploaded piece of work which oyu can click on and choose to upload into a different group, if you change oyur mind at a later date.
There is a 2 day waiting period between uploads, and old work will automatically move into your personal archive when you upload a new piece.
If you get stuck just give us a shout.

<Added>PS. Once you upload a piece of work it's worth putting a link to it in the Introduce Your Work forum so people can find it.
