Hi Cheri,

That depends on what kind of features you are looking to add and update for your Wordpress site. If you can provide a little more background information, I would be glad to offer what I know. 

A couple of notes to pass along. 

1. This is the go-to site for anything Wordpress related, including searching for plugins and widgets:
https://wordpress.org/plugins/

2. For reviews of Wordpress plugins and themes, check out this site:

Hope this helps!
