Here are the basic settings that I used on a Mac to record Skype conversations using SoundFlower, Skype, and Audacity.
Default Input: SoundFlower (2ch)
Default Output: Built-in Output
Audio output: SoundFlower (2ch)
Audio input: SoundFlower (2ch) (if you wan't to record both sides of the Skype call)
Built-in Microphone (if you only wish to record the other side of the conversation)
Recording Device: SoundFlower (2ch)
Playback Device: Core Audio: Built-in Output
You could record many other things using similar configurations. Happy Recording!
Update: Since writing this I happened to come across another tutorial on doing this with pictures, that you might wish to follow.

Social networks tend to have people that fill positions within the community. For example, within an academic community the roles of being a professor or a student can sometimes be identified solely by using the directed interactions among the individuals. To perform such an analysis, some measure of equivalence is used. In Social Network Analysis by Wasserman and Fauts, the following definitions of equivalence are reviewed (each with a note):
- Structural Equivalence - requires identical ties to other identical actors
- Automorphic and Isomorphic Equivalence - requires identical ties to other actors
- Regular Equivalence - actors have identical ties to and from equivalent actors
- Local Role Equivalence - actors are role equivalent if they have the same role sets
- Ego Algebra Equivalence - based on algebra of relational structuresSo, why is knowing how to use this important? Well, say you would like to better understand the network surrounding your blog by learning which other blogs are similar in their ties as you, then this is how you could do it.
