Thanks!

But I'm not sure I get this... I've read about transaction fees on the wikiw: https://en.bitcoin.it/wiki/Transaction_fees and I understand that there is a mandatory fee on very small amounts, less than 0.01. But even if this has changed, the error message I get tells me that the amount I'm trying to send, 0.01 BTC, is over the size limit. What size limit? Does this refer to the "blocksize"? The wiki says "0.01 BTC fee per kilobyte of transaction, but: If the blocksize (size of all transactions currently waiting to be included in a block) is less than 27 kB, transactions are free." Have I come above 27 kB? How do I know the blocksize?

Are other people able to send 0.01 BTC without paying fees?
