Anyone who is using Contribute for Blogging (and that seems to be very few on
this forum) will realize something very quickly: there's no user preferences.
This hasn't been developed yet, and tech support has admitted this.

In order to change preferences, something as simple as using the font menu,
you have to open up the bloghub.csi file with a text editor and alter the code.
Now, that's enough to scare away most people who simply want to write. It is
startling that Adobe has released this product as is.

Once you've changed the items you need (by changing the value from 'false' to
'true' or vice versa), you have to delete the Bloghub.csi preferences file. For
Mac users, that's in the Home/Library/Application
Support/Adobe/Contribute/Configuration/Blog Preferences folder.

It cost $200 Cdn for this program. Most Blog Editors are free. While there are
nice features to Contribute, this "beta" version is unacceptable---especially
since Tech Support couldn't provide these answers. I stumbled on this solution
myself.
