What are we doing:

Fills array of all tiers addresses for any tier of crowdsale. For 1-tier contract with address x it will be [x].

Update joined crowdsales by method signature

1. Open MetaMask Chrome plugin

2. Connect to the network, where the crowdsale contract is deployed. For example, mainnet.

3. Choose an account, which is the owner of crowdsale. This account should has sufficient balance in this network too.

4. Send transaction to the address of the crowdsale contract with the data = 0x04fc7c6d + hex(number_of_tiers*32) + number_of_tiers + address_of_a_tier.

where hex(number_of_tiers*32) - hex(number_of_tiers*32), normalized to 32 bytes (required number of zeros before address). For example, if you have 1 tier number_of_tiers*32 = 1*32 = 32. hex(32) = 20 and normalized to 32 bytes will be 0000000000000000000000000000000000000000000000000000000000000020

number_of_tiers - number of tiers, normalized to 32 bytes (required number of zeros before address). For example, if you have 1-tier contract it should be 0000000000000000000000000000000000000000000000000000000000000001;

address_of_a_tier - address of a tier, normalized to 32 bytes (required number of zeros before address).

For example, if you have only 1-tier crowdsale contract with address 0x1c6d46dedd61ef982f0938e73975404b8de6d739, the data should be: 0x04fc7c6d000000000000000000000000000000000000000000000000000000000000002000000000000000000000000000000000000000000000000000000000000000010000000000000000000000001c6d46dedd61ef982f0938e73975404b8de6d739. Amount to send should be 0.
