In this poster we present three developments related to the GalacticO-Star Spectroscopic Survey(http://adsabs.harvard.edu/abs/2011hsa6.conf..467M{GOSSS}). First, weare making public the first version of MGB, an IDL code that allows theuser to compare oberved spectra to a grid of spectroscopic standards tomeasure spectral types, luminosity classes, rotation indexes, andspectral qualifiers. Second, we present the associated grid of standardstars for the spectral types O2 to O9.7, with several improvements overthe original GOSSS grid ofhttp://adsabs.harvard.edu/abs/2011ApJS..193...24S {Sota et al. (2011)}.Third, we present a list of egregious classification errors inhttp://simbad.u-strasbg.fr/simbad/{ SIMBAD}: stars that are or have beenlisted there as being of O type but that in reality are late-type stars.
