Multiple "Forgot Password" submissions from someone else

[Bazar6]

My account has 3 users underneath me, with individual passwords set up for each, and my account is the admin with it's own unique password. I have not given anyone my username before, and definitely not my password.

Last night I received "Forgot Password" emails from my admin username and one from one of the users set up (since I set up the users with my email instead of theirs, to keep control over it). I did not submit the Forgot Password request for my name, and the users with access to the other name did not submit the request either.

Could someone have been trying to access my account without authorization? Did anyone else receive these requests for their account (wondering if it's possibly an attempt at a hack on the site, or just screwing around with my account).

I did change my password last night after confirming with the other users I have set up; you can never be too careful.
