The code for the username block warning is here: https://github.com/SharpScratchMod/Sharp/blob/master/src/ui/parts/StagePart.as The code for checking for the username block is here: https://github.com/SharpScratchMod/Sharp/blob/master/src/blocks/BlockIO.as#L95 All that needs to be done is to modify it to check for http blocks as well.
