This is a very good question. It helps to bring everyone's attention to the great tools at our disposal.
Before I give my answer, I would just like to agree with a previous member that Ask SC should be included in the Power Tools as it is the best training tool here (in my opinion). It has a wide range of answers which depend upon who is asking and who is answering which makes it the most dynamic Power Tool at SFI.
Now...because Ask SC is not in the Power Tools tab, I will give you my next best answer.
I believe the most powerful tool in the power tools tab are the PSA and CSA mailers. My reason for this is simple:
I am fairly new to SFI (3 months) and am always learning new things all the time. I must assume that my down-line are in the same position as me and could use all the help they can get. I am constantly scouring the internet for new ways to help me get my SFI message across to as many people as I can and as cheaply as I can. Every time I find such information, I communicate it directly to my down-line. This way I can ensure that as I grow stronger so are my down-line. Some of them will better utilise the tools I have shown them and others will write to me to ask me to explain them further. Either way, I am building a relationship with them and they are benefiting from my communication.
To summarize:
Communication is very(if not the most)important attribute to team building. Therefore the mailer is the most powerful tool at my disposal.
This is a very good question. It helps to bring everyone's attention to the great tools at our disposal.
