Problems of the first evaluation.

We did a summary with a power point explaining all things that we did in the first evaluation with a recording. To start with the work, after we did the power point and the recording we had to upload it to a program of internet called Slideshare, but we had some problems in this process. So we get up the work with google docs, and finally we present the work in our blog. If you want to see the power point  click here and also to understand better you can hear the recording here.
