I program in HTML,CSS,PHP For ScratchBook
However need more devs
For applying to be a tester
Go and visit my site dev123network.weebly.com/scratchbook
Click apply link
Type in da stuff
U might be accepted or not

What is it?

Its technically like Skype with Forums live chat-Followers Youtube vid links and all sorts of stuff
With Private MSGing and literally Scratch-Social way

This may not be a good idea, due to the fact private messages are hard to moderate, and an entire site in general could be unsafe.
