I searched a while for this. I want to be able to increase the upload size for files on a wordpress blog. This comes in handy for things like music sets, or larger images. I usually use FTP, but I want to add users to also be able to contribute larger media files without having them have to figure out FTP stuff.
Turns out that PHP is configured to have upload limits, the limit does not have to do with wordpress.
Found this sweet post which had a solution that actually worked.
yeaaaa!!! Expect to hear lots more PC//MM music now. And probably other things too.
