Can't stand childish bickering but constructive criticism must always be welcome most of us have a specialism in something so if your an expert in stock repairs and you see someone's DIY repair you don't like then, then either lie through your teeth and say its lovely, don't say anything at all, or explain in an appropriate way how you might have approached the issue,

generally here i have been fortunate not to witness much bickering but we all have different idea's about how to go about things and all understand that practicable gunsmithing can be performed at a variety of levels, while best quality work is always going to be preferred sometimes its just no viable economically or otherwise it should and could be a good resource.
