Re: So, I'm making the website!
My friend says she has the code for the browser-based IRC client. IMO -all- browser-based clients are crappy, because they annoy me, but I've used more annoying ones in a pinch. Honestly, if you use the chat for an extended period of time, you're likely to get an actual IRC client just for more functionality (because NO browser-based client has more functionality than a standalone one, whatever you do).
The Garnet Host: The benefit is that anyone can pop into the chat if they feel like it, straight from their browser, even if they've never used IRC or ANY chat before. Like I said, though, if they decide to stick around, they will probably get their own client.
A webclient and encouragement to get their own client, even if just to give them other options to access the chat (I hate browser clients and prefer mIRC just like some people hate mIRC and prefer Trillian) might be a good idea. Plus the option to use a standalone client = more features that browser-based clients don't provide, like aliases. More options, more features = good!
Edit: Oh, and the one my friend has is free. She can get the code for me whenever, if you'd like to see it.
