You only get the chance to have your say about this every four years, and the Electoral Commission wants to make sure you have every opportunity for your voice to be heard this Thursday.

So if you've decided to vote, or if you're just interested in how everything works, here's their insiders' guide to exactly what's involved. If you haven't voted before, why not visit www.aboutmyvote.co.uk / www.fymhleidlaisi.co.uk.

Where are elections taking place?

There are elections in all 22 local authorities across Wales on May 1 2008.

Who are we voting for?

The elections are to choose local councillors. These councillors are the people who represent your area on the local authority on a huge range of subjects which affect your everyday life – from leisure and recreation to local planning, rubbish collection and transport.

What are the voting hours?

Polling stations in Wales will be open on May 1 between 7am and 10pm. When you arrive, you will be asked for your name and address or the number on your polling card (if you have brought it), by the person behind the desk. They will then give you your ballot paper.

Where do I go to vote?

The most common way to vote is to do so in person at your local polling station. This is generally a school or hall near to where you live. You have to go to a specific polling station – to find out which one, take a look at the poll card you should have received through your door, or contact the electoral services department of your local authority.

Who are those people outside the polling station who ask you your name?

They're called tellers and they represent the candidates. They like to know who has voted so that they can keep track of how many more people may yet be due to vote later in the day. They will ask you for your name and possibly for the number on your poll card. It is up to you if you tell them, you don't have to.

What if I'm using a postal vote?

If you've applied to have a postal vote, this should be with you shortly, or have arrived already. Complete the postal voting statement with your date of birth (NOT the date you sign it!) and your signature, and post it or return it by hand to your local authority offices. Alternatively, you can hand it in to your local polling station on May 1. Postal votes have to be received by 10pm on May 1.

What if I'm using a proxy vote?

If you have applied for a proxy vote (where you appoint someone to vote on your behalf at your polling station), just tell your chosen proxy which candidate your wish to vote for.

How do I fill out my ballot paper?

When you receive your ballot paper, you put one cross next to the name of the candidate you wish you elect.

Some authorities have what are called multi-members wards, which means you may be voting for more than one person to represent you, so read your ballot paper carefully.
