Attempted hack?

[iPodVT]

A few hours ago I received three emails from "Rockbox Technical Forums <rbforums-noreply@rockbox.org>" over the span of about four minutes with the subject "New password for Rockbox Technical Forums".  All three emails stated "This mail was sent because the 'forgot password' function has been applied to your account. To set a new password, click the following link:  https://forums.rockbox.org/index.php?action=reminder;sa=setpassword;u=[I have excluded this 'u' for the purpose of posting to this forum];code=[I have excluded this 'code' for the purpose of posting to this forum]".

I was not using my computer at that time and didn't see the emails until a while later, and I don't recall clicking any 'forgot password' links, or otherwise trying or needing to reset my password.  Somewhat later still, I just now successfully logged on in the usual way with my longstanding username and password in order to post a reply on a different forum.

This has raised my concern that someone might have tried to hack my account.  Can anyone (a developer, I presume) confirm whether or not these were legitimate emails from the Rockbox Forum?

Thanks.
