Is there anything special one should be doing if one has supernet in the original NXT wallet since the token exchange?
Seriously, can someone answer this for me? I do not have any familiarity with NXT.
As long as your wallet is up-to-date to the most recent version 1.4.7 I don't believe you have to worry about anything.
That is if you already redeemed your SuperNet Asset for the Token Asset(when it was being sold). If not you have to convert it over to SuperNet.
If you want to actually "use" SuperNet you need to download the modified NXT wallet.
