Well, it would be cool, and you could make chats private, or have a huge 'meeting' kind of thing saying important stuff, and have problem solving. You can talk to other people about designs and stuff. On the site though, have a different page.
I'll be looking forward to one of these, sooner or later. Or possibly I won't. If it gets rejected.
Pilojo, every language has vulnerabilities, and vulnerabilities don't have anything to do with the language itself. PHP offers freedom, flexibility and ease of use unparalleled by any other language, almost all of its "vulnerabilities" are PICNIC(HOW MANY TIMES HAVE I SAID THIS?!). If a language didn't allow you to create a script that could be exploited, then it would be so restrictive it would never be used.
