@MarsC & @Klogg
The way I got the list of clients is exactly the way @Klogg described it.
The only difference is I used Excel to remove all of the HTML tags.
You can redo this exercise every few months and slowly build a chart of ASW's client numbers (and also its competitors' if you want), and see the trend of clients acquisition rate, i.e. which company has more success in securing new clients.
