Fixed Avatar Transparency

That would be imagemagick/gd doing its thing. http://www.imagemagick.org/discourse-server/viewtopic.php?f=5&t=7120 Looks like a bug in the transform perhaps?
Isn't there a way to reduce the PNG file size? Really small PNG's (even 24bit+transparency) are entirely possible without losing quality. Were you trying 8-bit indexed or 24-bit PNG's?
Not that I'm blaming you, it's probably entirely GD's fault, but if you could maybe work a little bit harder on it... well, full-transparency uploads would be awesome.

In general I agree, but for webdesign that's not always the case...

No, different image formats are suitable for different applications. Use the right tool for the job instead of just saying X is always superior. For example, PNG is lossless and performs well for many applications. JPEG is lossy, but performs much better in terms of filesize than PNG for photographic images, while maintaining the same visual quality in terms of what the naked human eye can detect.
To be clear, is this a limitation of the forum, or just the fact that the server is using GD? My forum uses GD and I do not have this problem.
Just as a test I changed my avatar to a 200x200 PNG and it looks like someone turned off the lights.
If it is a forum limitation than that is a instant deal breaker, considering transparent avatars (and images in general) have moderate popularity IMO and about 90% of general forum users do not use their own photo.
Floris, I like you, I really do. But telling people to upgrade isn't solving the problem. GIF isn't dead and saying that it is, is well, ignorant. I use a modern browser on a modern operation system on modern hardware and having my avatar turn into a black box would still be disappointing (which it is). BTW: What does a browser have to do with this thread at all? If anything you should argue that filesize isn't a problem since modern computers and internet connections are fast enough to handle a transparent PNG avatar

Did you try using these features when you said that "the files were huge"?
