I would like to congratulate and thank the Construct2 developers on really checking on the size issue. The Construct 2 IDE itself is relative small in size ie 28MB, the plugins are only KB's in size and finally the website, it only eat less data usage because of less picture and more contents/words.
I think this is the reason why there are many forum user online and registered because there wont mind on internet data usage consumption. That said, Well Done to the Scirra Developers.
