What places are the FH center listed so I can edit the hours, etc.?
The article Barry Johnson suggested also has links for the CDOL and the WIKI, both need to be updated for your hours and contact information. In the WIKI article it will show you how to ask for editing rights.
If you have any difficulties, please feel free to call Tech Support at 866-406-1830, select option 1 for English the option 5 for Family History Center Help.
You can find a list of family history centres under the help icon (?) at the top right of the page, but you won't be able to edit anything there.
I have a attached a Knowledge Article which should give you the guidance you need. Just click on the link, or copy and paste the URL into your browser.
Hope this helps.
