Conditions for all potential users:

1. The VLBI network will operate under guideline similar to the ATCA and Parkes. There will be no absentee observing and proposers are expected to participate in the observing. Personnel requirements can be quite large i.e. at least 1 person per antenna for each observing shift. To simplify observing arrangements, proposers will be required to observe at one antenna only but for $n \times$ observing shifts, where $n$ is the number of telescopes requested in the network. The VLBI coordinator will coordinate the arrangements for observing.

2. Use of antennas which are not part of the National Facility require the cooperation of the home institution and such permission is the responsibility of the proposer. Detailed information and contact persons may be obtained from the VLBI scheduler, who will assist with overall coordination.

3. Disks for VLBI recording (XRAID) are in limited supply and proposers may be required to provide additional disks for special observations with extreme recording capacity needs.

4. Mk4/5 recording systems are available at some antennas (Table 1). The Network can schedule these, but the provision of Mk5 disks and correlating is the proposer's responsibility and may need special arrangements. The VLBI scheduler can provide information and guidance.

5. The LBADR disk-based recording system has now been adopted on the LBA. The tape-based S2 system has been decommissioned from the beginning of 2007.
