I bought my eos tokens directly from eos.io official website using ethereum out of my 'metamask' wallet. Once you "register" your wallet with the eos.io website, then all the tokens connected with that wallet are included in their "snapshot". The major event will be June 1, 2018 when EOS erc 20 tokens are retired. Then BLOCK.ONE will take over. As I understand it though, apparently as early as Feb, 2018 there may be also be earlier "airdrops" into our registered wallets as various new developers get ready to launch their applications on the new "BLOCK.ONE" block chain. so it sounds like there will be earlier snapshots too.

I had a question earlier: "What would be the purpose or reason for "claiming" eos tokens if they were bought using ethereum directly from the eos ico distribution (not exchange) using metamask wallet and then 'registered' this wallet with eos (double checked to confirm was registered the next day)?"

I do not intend to 'transfer' the eos anywhere else before June 2, 2018 ( the date that the eos erc20 token is set to become retired or obsolete so to speak. Their website allows for a 'claiming' option if you wish to transfer the eos you purchased. A clarification regarding "claiming" is on the eos.io official website as follows (copied):

                             "CLAIM

EOS Tokens will not automatically be transferred to the Ethereum address used to purchase EOS Tokens. EOS Tokens can only be claimed after the period pursuant to which you have purchased your EOS Tokens has ended. If you want to transfer the EOS Tokens before the end of the EOS Token distribution, the EOS Tokens will need to be claimed. Otherwise EOS Tokens do NOT need to be claimed."

....so as I understand it, if I intend to 'hold' the eos tokens that I purchased directly from eos during the ico distribution, then 'claiming' does not help me nor is it necessary.
