Hi Yang, Illumina keeps changing their naming schemes for the probes so it was getting tricky using those as the identifiers. BeadArray switched to ProbeIDs and it seemed like most people (including myself) were using those so I switched. You do not need to use the existing platforms in GEO. You just need to include an extra platform file when you submit which includes the ProbeID and one or two annotation columns. You could use the accession identifier and gene symbol for those.
