My colleague (and mentor) was the creator of UTBuddy. It was a buddy list for you to see where your buddies last played UT and how long ago. He spent many hours on it, even creating little neat graphics for it along with taking in some beta feedback. Many research hours were spent, all for a program to be handed out for free. I know what it's like to create something cool and sharing with others. Many programmers know this feeling. You do things to challenge yourself and keep your skills fresh, all the while making something simpler for someone somewhere.
With that said, good job on your new creation. I'm glad you created something useful (and making it available free of charge). Don't mind some paranoid freaks on this forum. Some people need to learn to criticize without calling people names. You can't expect 100% maturity on an internet messageboard.
As for UTBuddy... the server that housed the server-side code had a harddrive failure... and being a guy that lived on the edge... he didn't have anything backed-up. Hundreds of users were out of luck. The proggy was noted on the front page of PlanetUnreal.com at one time. RIP UTBuddy. Good luck with MessageServer. Hope you get a nice following.
