I mistakenly signed twice. Will there be a duplicate check, or could you simply remove my second entry?
[I forgot I had NoScript enabled, so after the first attempt nothing seemed to have happened. That's why I disabled it, which refreshed the site, and submitted again. Then I saw that first time worked already, so now my name appears twice.]
The epilogue reminded me of a funny quote I've heard in a conversation about Computer Security and Encryption:
"If brute force isn't working, you're not using enough"
The link from this reply now posts to a steroids page. From the DOI in the link, I found the article here:
