Classic British Flight Sim

Hi,
As a user of Vatsim, I wonder if somebody can advise me on which call sign to use on CBFS VA?
At present, I tend to substitute the CBFS flight number on the fsa with BAW and use 'speedbird', even on the shuttle routes.
Any suggestions to add credibility to my online flying....Speedbird 2222 was a bit of a mouthful!
Thanks guys.

When I was flying for the VA, I used "CBF" as the identifier and "Bee Line" as the Callsign (put in the remarks as - RDO/BEE LINE)

As CBFS VA isn't a partner, there's no official callsign registered so you don't have to adhere to the same requirements as VA partners do (like using you VA ID as the flight number at all times), so just make sure whatever you use is recognizable to yourself.
