okay this has probably been discussed and resolved a hundred times but in a fast search I have found nothing about it!

this split album
http://www.metal-archives.com/albums/Fu ... nce/155867

features three bands,
Mrok is a dark ambient polish project so no metal no page and no member

the other two bands feature niklas kvarforth,
for what concerns the Shining part the split contains two songs from their two-songs debut EP and for what concerns Funeral Dirge the split features,.. again two songs from their two-songs debut EP

so, how to add kvarforth to the two bands?

Within the current constraints of the site programming, you can't. You'll just have to mention the lineup in the additional notes or something.

It seems like a low priority, but it'd be a nice feature to have. I've come across a handful of splits that are based around a member (or members) in two different bands

Thanks for the answer .
