I wanted to add a Like Box at the sidebar of a website hosted at Google Sites. However, I learned that Google Sites sidebars do not accept custom codes. I have verified that myself because I tried to place the Like Box onto the sidebar before Googling an answer for it when I found that it won't work.
However, the Like Box might just work on a page itself through a Google Gadget Editor, as discussed in the Google Sites Forum. But I do not want to place the Like Box on a page....
In the meantime, I have found out that a Facebook Banner will work on the sidebar. I'm just not sure yet if the "status" line will update itself, because I've found out that this does not update in Blogspot.
If that does not work, then I will just chuck in a "Find us on Facebook" button instead.
