Totally agree with you Ian, this place has always been about exchanging of ideas, help and opinions, it has been that and I have benefitted from this a few times. Without knowing what has transpired this past week I guess it come down to respect... unfortunately it seems you need to have this 'guideline' or 'rule' nowadays, online intimidation, rude comments or insults has become a real problem and can sometimes make a nice community or forum a unpleasant place to visit.
