One of the issues which people faced is that the powerpoint slides which they constructed is too big and cannot be sent via email.
I have screencasted a demonstration on how we can use the Compress Media feature to compress the media. Notice that i cut down the amount of disk space i need. From 37.7MB to 9.17MB.
You can download the sample here.
