A friend of a teenage girl missing from her Essex home has set up a website in an attempt to find her.
Natasha had called her parents to say she was on her way home
Natasha Coombs, 17, has not been seen since boarding a train to her home in Dovercourt from Ipswich, in Suffolk, on 27 July.
Police believe she got off the train at Manningtree, Essex, and have traced her mobile phone signal to the area.
www.findnatasha.bebo.com, which was set up by Joshua Nellie, has already received more than 3,000 hits.
Joshua, from Ipswich, said: "I have seen bebo is quite a handy website to attract a lot of people on to various sites. There is one for Madeleine McCann which has been very successful.
"As soon as Natasha went missing I did not think it was fair to wait about, something had to be done straight away.
"Two days after she unfortunately went missing I set the website up and six days later 3,000 people have looked at it."
Joshua said many people had left messages of support to Natasha's family on the website.
Footage of Natasha boarding a train at Ipswich station on 27 July is the last confirmed sighting of her.
On the night she went missing, Natasha's father texted her to ask if she wanted to be picked up from Dovercourt train station.
At 2301 BST she replied to say she had booked a taxi.
Police are trying to establish which taxi firm Natasha called and are appealing for people who were on the same train as the teenager to contact them.
