This section is fantastic but I've been asked by a few of you here about uploading sound clips, so I've allowed mp3 file attachments with a maximum file size of 512kb. That's more than enough for sound clips. But if you can upload clips between 96-128kpbs, joint-stereo and variable bitrate, that would help keep the file sizes down (if you can't do VBR, 96kbps-128kbps CBR is fine too).
If you want to upload something larger, I would HIGHLY suggest using the built in Windows Movie Maker or the built in movie maker on Max OSX and turn your sound clips into a video that can be tossed up on youtube. Otherwise there are many other places that can host and share mp3s. I just wish I had more disk space and bandwidth on the server (the ad revenue barely covers the server).
Anyways, I hope to check out the sound clips demoing some of the pickups in this forum!
