Week 2: Wimba

Copyright issues are a topic I don't know if I will ever truly understand completely.  I do know that if I don't create it, I don't own it and I need permission.  There are some Fair Use areas that give us, especially as educators, some leeway with usage, but we must be careful.  Creative Commons has enabled to protect the rights of the creator and allowed the user some freedom to use so much wonderful creativity out there.  But as educators, we must be most careful how we use copyrights in the class, so we basically do as we say! We are setting examples.  So I need to know what is correct and right.  With that said, I wonder if when I used the Twitter logo if that was a copyright infringement?  Can someone answer that?  It was for an educational purpose.
