The appropriately named YAC, a UK-based telecommunications company, has launched a service that allows companies to hold teleconferences without setting up an account. Potential users can set up a conference through YAC's website, www. yac. com, by entering their credit card details.This is in contrast to standard procedures, which usually require customers to go through a two-week process to set up an account. This would suit a regular user of teleconferencing, but would be frustrating for the one-off user who suddenly realised they needed the facility.Charges for the YAC service are by the minute and are, claims the company, about 25 per cent less than BT.
