UPDATE

Added transaction handling.  At http://88.198.210.245:7875/ you can see how it's implemented in the interface.

How to send money
1]  Go to http://88.198.210.245:7875/
2]  Click the orange lock to unlock an account
3]  Enter any digit into SECRET PHRASE field, for example "1" (the genesis block contains only 10 addresses with 100 mil coins on each)
4]  Click the purple arrow in the top right corner
5]  Fill the form, amount must be not greater than 10,000 and fee not greater than 100 (limited for testing)
6]  Deadline (in hours) can be less than 1, enter 0.1 to set it to 6 minutes
7]  See the balance adjusted and the transaction appearing in the unconfirmed transactions list

If a transaction is not included into a block (it's not because mining is in development yet) then after the deadline is reached it will be removed.  We tested that transactions are correctly propagated over the network (sent some from one peer and watched them appearing on another).

Now I'm working on the most interesting part -- the mining.  Stay tuned.
