I think both Joel Yocom and Denis Meloche are correct in that communications and information are essential but we must avoid the risk of commercialization and abusing the technet facilities. Why not adopt the practise of including a telephone number on all such supplier info requests and keep the responses off the network. The responder then has a choice of e-mailing or telephoning the info. Where the request and response is generic and not referring to a specific supplier, the technet is invaluable. Re circuitry suppliers of all breeds ---- the IPC Membership Directory does list facilities and capabilities. I don't know where any central info source exists for fluxes, etc. Bernie Kessler
