Hi Shakira, Thanks for contacting us. You should be able to simply click the Bold button on the Text Properties dialog which appears when you click your text. Are you able to find this button but it’s not working? Or is the button disabled? If it’s disabled this means that there isn’t a bold version of that particular font available.
If it’s enabled but not working, please try closing down your browser completely and re-launching Ribbet. This restarts Adobe Flash and should resolve the issue. If you continue to have a problem you can contact us here and we’ll help you sort it out one-on-one.
