73 * To cut down on the amount of commands services etc have to recognise, this only sends METADATA across the network now
74 * not an actual SWHOIS command. Any SWHOIS command sent from services will be automatically translated to METADATA by this.
75 * Sorry w00t i know this was your fix, but i got bored and wanted to clear down the tracker :)
