Google offers some cool gadgets that will work on our Ning Networks. I have attached a text file that contains the code. This code is for a clock that will fit in the right column. All you have to do is: add the code to a text box.
Also, here's the Google page link, where you select other gadgets. Not all will work within a Ning Network. But, for sure, you can customize your clock size and colors:
Google Gadgets

Be careful, the gadgets are created by Google users, not Google. Personally, I would not use the gadgets that have Google Ads embedded. The gadget creator is making $$$ off your site visitor's clicks. If you do not pay premium service from Ning, you could be violating their TOS.

I will add more of the gadgets that work, to this Group. I am adding a secondary text file that contains the code without the "Google Clock" title. I tested it, and it works for me.
