Comic Relief's Red Nose Day website has proved a hit among surfers.
This year's Red Nose Day theme is Big Hair
The UK site has received more than 15 million page views since it was launched in early February.
So far 300,000 people have been to the site, with many of them making return visits.
The site focuses on the events leading up to and around Red Nose Day on 14 March, as well as providing education packs and fundraising ideas.
The website has a sophisticated system for online donations to cope with the expected flood of visitors.
It is capable of taking 200 transactions a second, which is similar to the amount a major bank handles on Christmas Eve.
For the first time, donations can be made in other currencies such as euros and US dollars.
As well as asking for your money, the site is streaming live feeds from the BBC's Fame Academy, where a group of celebrities are trying their hands at a singing career.
Visitors can also purchase red noses, car badges and Spirit in the Sky CDs, the official single from Gareth Gates and the Kumars.
Last year £3.6m was donated via the Comic Relief website. During the live TV transmission, the website became one of the world's busiest e-commerce sites.
This year's campaign culminates on Red Nose Day on Friday with a night of live entertainment, broadcast on BBC One from 1900 GMT onwards.
Since its launch in 1985, Comic Relief has raised over £250m to combat poverty and social injustice in the UK and Africa.
