Totally Doctor Who wants you!

New CBBC show wants to hear from young fans of the Time Lord.

CBBC's new Doctor Who-themed magazine show will be called Totally Doctor Who - and the programme team want all young fans out there to get involved.

Totally Doctor Who are recruiting cadets for a Companion Academy. Eight Cadets will be picked, but only the best will make it through the gruelling physical and mental challenges of the Academy. The prize? A day on the Doctor Who set.

Or if you think you're the biggest Who brainbox around, take the Who-ru challenge. Stump the Totally Doctor Who studio guests with your Who knowledge and you'll walk away with some serious prizes.

And Totally Doctor Who also want to hear how much you love Doctor Who. Have you built your own time machine or held a Doctor Who fancy dress party? Send in your photos, videos, stories, pictures, or anything else.

Plus, if you've got a burning question you want to put to Doctor Who cast or crew, send it in and the Totally team will do their best to get an answer.

How to get involved.

To enter for Companion Academy, send a video of yourself, no more than a minute long, explaining why you'd make a great Cadet. Previous time-travel experience isn't essential, but you must be between 7 and 12.

For Who-ru, send in your three best Doctor Who facts (all about the ninth and tenth Time Lord).

Or just send in questions and cool stuff to:

Totally Doctor Who, PO Box 5158, CF5 9BD, marking whether it's a Companion Academy or Who-ru entry,

or by email to totallydoctorwho@bbc.co.uk.

If you're sending a video, make sure your parent or guardian gives their permission in a letter. Send it in along with your tape.
