are we allowed to/is it possible to post mp3's? i havn't tried yet because i dont want to get in trouble if its not allowed.

I suggest you to not, if it isn't your production.

even if its just for sampling purposes? the only mp3s that i would post would be off blogs so they are available to everyone anyway...

No , not all blogs are trustful....There are a tons of them that have malicious & illegel content on them...

Unless u are sure that some purticular mp3 is under free to use & distribute term
don't post them...

90% of the albums are not free to use,only very old or sometimes some artists make free production....

ok thanks
