HE in FE and email signature

It is amazing when thoughts go to cultural change... I have left off HE Operations (the department I work for) on my email signature as I fear that FE areas of college may present barriers to any requests or views on Technology Enhanced Technology I may make. Is it just me or do I need to be careful about my identity (whether more HE than FE?) when trying to encourage change in a mixed HE and FE 'community' college?
