M1A=貨幣機構以外各部門持有通貨+支存+活存
M1B：也是狹義的貨幣供給額，是除了 M 1 A 的各項流動性資金外，再加上金融機構中的活期性儲蓄存款資金，這部分資金變動性最大，政府部門一向將此視為民間經濟性
金融交易活絡的重要指標，也是行政院經建會在計算景氣領先指標時，最主要的貨幣指標。M1B=M1A+活儲
M 2 ：為廣義的貨幣供給額，代表全體貨幣機構的流動性，包括一切貨幣（現金、活期存款外及各種存單等形式存在的準備貨幣即定期存款、存款準備等 ）， 如果M2持續成長，代表金融體系存款增加，資金充裕，遊資安定，應可配合經濟成長所需的資金。 M2= M1B +準貨幣

SKYPE has a lot of good stuffs, one is SkypeIn, you can purchase a real phone number in 14 countries, let other people easily find you using normal telephone. (I'm using the SKYPEIN Australia number now, in case someday I send my CV to apply job, they can find me easily.) Another is SkypeOut, dial international physical phone numbers through Skype. A good function called Call Forwarding in SkypeIn, which can forward the missed call to physical phone number, it will deduct your SkypeOut credit while Call forwarding occured. When purchasing Skype Credit be careful about the currency you are using, better not use EURO as your base. If you are in Taiwan or Singapore, the exchange rate is not so good for EURO. I've checked the SkypeOut rate and connection fee, SkypeOut rate will be adjusted according to current exchange rate, but not for connection fee. So we'd better change the base currency to US dollars for earning the connection fee difference.
