Basically... I decided to stop playing MUDs, and uninstalled all three clients on my computer (was sort of a ragequit to be honest). However, I do want to pop back in and chat with a select group of people without certain staff members getting all "I TOLD YOU YOU'D BE BACK". Is there a page I can navigate to with a java or flash or whatever client that either allows for specific proxies or uses its own IP address to connect? I know there's one on MUDconnector or whatever it's called, but that IP was banned for whatever reason.
I'd laugh evilly, but my client isn't done yet, so I'll settle for a quiet smile. :) There's no client I know of that does precisely what you want, unfortunately, and even a client that did do that would need to clear it with the MUD in question.
Also, popping in with a proxy is probably a bad idea for all sorts of reasons. My web client is going to have a method to get the user's IP to the MUD being connected to, so it can't be abused.
