Look at my post on my home town, Leicester.
Now write a post on your home town. Make it as interesting as you can so that anybody reading your post would like to visit it. Try to avoid cliches such as: Bilbao is very beautiful or Athletic is the best football club in the world!
Think about how its population has changed in recent years, how do its immigrant inhabitants affect its life and culture?
Do a Google search or look up your town in Wikepedia to find information that perhaps you didn't know about and can improve your post.
But remember: no copying and pasting! Everything you write should be in your own words. And don't forget do do a spellcheck before you publish your post.
