Hi Heather, I've managed/seen many communities and the community name typically is placed in the upper left corner (where you can load a logo) and the company name goes into the footer. We've got tons of community screen captures you can browse through if you are interested. Check out:
- Examples of internal communities: Internal Communities

Be sure to click on the images in each of the posts so that you can see them larger and clearer. Cheers!
