Organisers of a Bristol Twitter festival are hoping to raise £3,000 at the March event for Concern Worldwide.
The event, which gives users of the social network Twitter the chance to meet each other, will be held at The Tunnels near Temple Meads station.
In 2009, the Twestival raised £1,500 for charity:water and this year has set a target of double that amount.
The Bristol event is one of some 200 taking place around the world on 25 March 2010.
Organiser Dan Martin said: "If this year's party is even half as good as last year's, everyone who comes will have a fantastic time!
"Our venue for 2010 couldn't be more perfect given the association with Bristol icon Isambard Kingdom Brunel, and we look forward to raising thousands of pounds for Concern Worldwide [this year's chosen charity].
"While much of the activity for Twestival is driven by Twitter, the event has a real community feel and is a great way for the people of Bristol to come together on the same day as communities around the world to raise money for a great cause."
Organisers have also announced local band Phantom Limb will be headlining the festival.
The band recently featured on BBC Bristol Introducing and
performed a session for the programme
The event will also feature a chance for attendees to win shopping vouchers and games consoles.
