I got a tweet back from Era about the "ERA" on stocks.exchange and it is still BLAS, listed as ERA, so you would have to go through the process of withdrawing, and converting.. 

My personal opinion is that the ERA project does sound ok, but going through the process, and reducing my coin count (which is a good thing for increasing long term value) is not for me with the market the way it is, and as such i sold my position for someone else who is keen to do this, and gamble on what price ERA may stablise at after april 10th. I say this as I went through a similar process with B3, to KB3, which ultimately was a headache, and i think i lost even more money given the time and effort it took, and that was when the market was still bullish.   I look back now, and i really wish i had sold my position on B3, rather than go through the coin swap, numberous wallet updates, then to see it get delisted from the stock exchanges, and now wound up with some coins that i can't really do anything with.

Best of luck to those people willing to go through the process, and best of luck to the ERA organisation, and please understand the comments above are my personal opinion and experience, and do not reflect badly on ERA, just the amount of effort I am prepared to put in for what would be an unknown reward.
