shouldnt you state the version your ext was tested with

[BaconFries]

This idea has already been implemented but it does need the input of all the extension builders to do this at present I am working my way trhough all my extensions rebuilding to suit 6.5 although one or two may not meet W3C standards due to the use of JS this is because the validator doesnt understand the code and reads as errors but it still fucntion fine take a look here at what you asked this shows what extension builder was used to build the extension 2.0.2 is the latest compatible with WB 6.5
