How about a sticky with all of the known bugs in Data Bridge and Design Extender?
Just a quick suggestion to start a thread that contains the known bugs with these two extensions (there seems to be a host of them) so that your users can see what they are up against, rather than read 1,000,000 posts that all have the same few error messages listed.
Open and honest is a good idea to save us ALL some time, including yourselves in relation to answering the same question every few minutes.
