Where. once you have selected a ticker at any of the ticker sites, you can copy and paste that ticker code (use the code for bulletin boards, "BB" which you see is enclosed with brackets [ ]
If you get it right, when you save the changes, you will see your ticker appear on all your posts. Whenever you want to change the weight or other info on your ticket, you go back to the ticker site and enter the new information. Ticker Factory provides automatic updates, so that you need only update the info at the Ticker Factory site. In other words, you'll not have to go back into your SLD Profile to make new changes. Unless you select a ticker from another ticker website.
