Hi,

before I got to register a Zotero account my husband has put up a Zotero group and put me in as member, anticipating a user name which I should use. I couldn't use this name when trying to register because the system thought that the name is already used. I can't use the lost password feature, because no mail address is linked with the fake account. Worse, I had already entered this user name in the sync settings. Later on, I've registered with another use name.

My problem is now that I can't change the user name in the sync settings, because my libraries would be deleted in the process. I've already tried to backup the data directory and put it back in place after setting up syncing with the new name, but then the settings switch back to the original user name.

Is it possible to somehow merge the two accounts so that I don't lose all my work?

The unusable user ID is 5771264, the new one (for the account I'm writing from now) is 17520261.
