1: Okay yes, this is very ugly. I had it kind of nice and then
2: I decided to go all out and compact it a lot. So here is a
3: fully-functional CGI script that allows anyone to come in,
4: enter any name they want (yes, even multiple instances of
5: the same nick are allowed) and chat together. It does use
6: two small pieces of javascript: one to refresh the chat
7: messages (because inserting that meta tag in the HTML
8: headers would have taken more space) and one that sets focus
9: to the chat box when you put your mouse over it.
10:
11: It doesn't really fit in the category of obfu, but it will
12: look better here than anywhere else. Code is for reusable
13: stuff, same with Snippets. I don't think anyone'll want to
14: use this!
15:
16: Features of the program? Only one: URL's are turned into
17: links ONLY when used in the perlmonks way (using square
18: brackets). And even then, it must be a URL between the
19: brackets and nothing else. No vertical bar to name the
20: link!

22: So here it is. All in 19 lines:<br>
