Yesterday I asked to remove one login that was associated with me and mentioned which one it was. I had two or even three. Now, I cannot even login with the one I wanted to keep. Apparently, you've deleted the wrong one.

Please restore my previous Confluence/Jira login "Saskia.siebeneicher". I know it was not smart of me to chose the same name again, but hopefully you're able to differenciate between the old one that I'd like to reactivate and the new one that I chose just today.  In case of further questions, please contact me via email. Thanks.
