I have been using a jQuery content slider called "bxslider". This however is now causing the "My Profile", "Invoices and Payments" to not display anything. As a workaround I am using the Wild Apricot Slideshow Gadget. I am taking the texts I wish to display, and saving them as a png file via Power Point. Maybe not the most efficient, but I need something up in a hurry and this worked. A big disadvantage of this method is that you can not have a link in the text, and not very scaleable.
I would like to suggest that Wild Apricot develop a gadget, similar to the Slideshow gadget, for text item. Need one that can display multiple lines of text, links, and possibly pictures. Should also be able to format the text individually, not as a whole, select a background, select how long a slide is visible, how fast it transitions and what type of transition. I'm sure there are a lot of other "options" (as can be seen by looking at bxslider) but this is a good start.

For my news ticker, I have a specific document template in Open Office (would work on Word as well) such that I create pages with the exact size of the area where I want the ticker to run. Document background color matches site background exactly.
Print these as JPGs using Paperless Printer (free).
Upload these to a directory in WA and then add to a slide show.
In slide show, you can add a link to each image.
