Total newbie question

There were some problems, but they seem to have been sorted. It does depend on the time of day you post. I quite often have a black-out between 2-5pm GMT. But what ought to happen you press RIFFLINK button [I log on to riffcast just in case] and up pops a screen for your browser. If you've some linux black magick going on, maybe that's the problem! Next you fill out the details, but in the description just keep the text in one line and don't press return [For whatever reason mine don't post when I do that. You can correct it later using EDIT in riffworks]. Finally, after filling in your user name and password and pressing agree, you'll see your song being played super fast as it uploads to the site, so the VU meter is going mad! After that give it like 20 minutes and it'll be posted. Hope that helps!

Thanks a bunch guys!

Can you give more details?

T4 should mix down to either .wav or .ogg files without needing anything else. Audacity's good for converting to .mp3 if you want to upload to other websites.

thanks will download today. Also how do I mix from 4 tracks then overdub more tracks or do I need to buy more stuff?

Unlike the old four track recorders where bouncing 4 tracks in to one to free up the other three was the only way to create more tracks than you physically had, RiffWorks can create many layers (up to 24 in any one riff block). Effectively, you can multitrack to your heart's content (as long as you have a good enough system with enough RAM).
If you want to make more than 20 layers per riff, bouncing things down as Bill says, will give you even more flexibility but, whereas you can control FX, volume, panning etc. on individual instruments (where each instrument has it's own layer), you can't do this on a bounced riff.

But he is using T4 which only has 4 layers per riff
