Gibbage is correct, there is, or always was, an unspoken rule about others work re developer to developer, there is some latitude to rival poking and joshing in a friendly manner, but it is a small group and it cannot sustain in house bickering.
Those that consistantly step over the line tend not to remain around for very long. Many developers move from design house to design house or produce work for several houses at once, it pays not to tick off those who may be your employers in the future

Anyway, very pleased to see Kevin stand four square and take it on the chin, perhaps some others involved should do the same and completely clear the air and stigmatism they migh have attracted.
