Do you mean registering in the WM Equity group site?
If it's so, then I registered from day one and I updated the amount while I kept loading. That's a done deal. I even sent the letter asking for the EC and contributed with some $ to get the press involved.
I thought you talked about asking my broker to get the CUSIPs numbers or something like that, to either prevent my shares to get used in shortselling or/and to have them more secured in case of litigation. This is the topic where I get a bit lost.
