Mass Resend Activation Mail : MyBB

I don't if this is the right place for this thread... Mods, please move it otherwise.

I have created a forum on tech niche. It's growing ... but I noticed that a lot of users have not activated their account. Is there any way I can mass-resend the activation e-mail?

Please help

Did you check if the register user is bot or not? Sometime bot register on the forum.

That's possible but if I resend the activation email again, the real people will get 1 reminder. Do you know any way to resend the activation mail?
