The BBC has a system of dealing with complaints from our audience. If you have a complaint for a CBBC show or website, please visit www.bbc.co.uk/complaints/

Not all online clips or epsiodes can be watched outside the UK because of copyright reasons.

The Horrible Histories songs are not available to buy on CD. However, you can watch all the songs on the Horrible Histories website.

Unfortunately, due to the number of requests we receive, we cannot provide autographs of presenters, characters or actors who appear in CBBC programmes. However, we do provide printout autographs for some of our famous faces on the CBBC Stars website.

To send a message to Iain, Hacker, Dodge, Chris or Ed, please email cbbc@bbc.co.uk

Shows which are currently looking for people to take part will be on the Be on a Show page. If a show is not there, it means that particular show is not looking for people to take part at the moment.

Watch out for trails on television or check out the Be on a Show page regular to find out when your favourite programme is looking for contestants or people to be on the show.

However, not all shows will advertise for children to take part but will have different ways of finding contributors.

Find out more about how we select children to take part in shows on the How we make TV page.

Getting into television is pretty difficult. There's lots of competition and it can be a matter of luck as well as ability.

Our advice for anyone wanting to get into television would be to get as many qualifications as possible. Broadcasting is a very difficult and precarious career. If you have exam passes and qualifications, you always have something to fall back on.

Another tip is to practice speaking in public to help build up your confidence. Working as a hospital DJ is a good example.

We do not publish auditions on the CBBC website. When a CBBC or BBC Drama is cast, the Casting Director speaks directly to a multitude of agents and agencies. The agencies then put actors and actresses forward for specific parts.

So, if you are interested in acting, particularly for CBBC, your best bet is to find yourself a reputable agent and ask them to put you forward for auditions.
We do not supply listings of agents or agencies. You could try looking contacting your local stage schools or drama group and ask them for advice.

Unfortunately, your favourite programmes can't be on all the time. Though it's not possible for us to tell you about programmes more than a week in advance, we do try and keep you up to date with what's on or what's new via TV trails and our presenters.

To check whether a programme is on, go to our What's On page - a guide to all the programmes currently showing in the next week on the CBBC Channel, CBBC on BBC One and CBBC on BBC Two. You can also find out more about individual programmes, including when they are on by finding them in the TV Shows & Info section in Watch.

To check what time your shows are on CBBC, you can look at the What's On CBBC TV guide. This is a guide to all the programmes currently showing in the next week on the CBBC Channel, CBBC on BBC One and CBBC on BBC Two. You can also find out more about individual programmes, including when they are on by finding them in the TV Shows & Info section in Watch.
