Hi, Terry, and welcome to WriteWords.
I see you've taken the initial steps to getting started - ie. joining a group, posting your work, and critting other member's work.
As Emma says, some groups are quieter than others, and you can join more than one, so feel free to move around until you find one that's more active. But, saying that, if you are active in uploading and critting, it will pull other interested poets into a quiet group and help to revive it.
Starting discusion threads in the topics section of the group will also bring in interested people.
You can also post a note with a link in Introduce Your Work asking for feedback on newly uploaded work - otherwise it risks being over looked in a quiet group.
If you have any questions, just ask.

<Added>I also see you haven't uploaded either of your poems in the group you've joined, so I would suggest you choose one of them, and do that now, along with a note at the top of the piece (or as a post in the topic section of the group) saying what sort of feedback you're looking for. If you don't ask for feedback, them most poeple will think you've posted it to showcase it, rather than for a critique.
