The faircoin balances are not yet there. But there are a "user notes" field
where you can add your notes.

Now is needed that everybody enter with their user, and add to the notes

"My faircoin balance from Mintpal V1 is lacking due migration issues.
You was migrating FAC, but the correct label in mintpal V1 was FAIR. You need to do this migration
in order we are able to withdraw our faircoins"

Also could be interesting to add your ticket number if you have one.
