i looked up the comic artist and looked at the "Better late than never" pool http://e621.net/pool/show/1188
however it appears to be three comics that make a whole.
Figure i would make a pool for each, but... lol i've never made one, plus its like 3 am here, i gota get some sleep...

anyway, i dont really know how to make, sort, edit a pool.. an also want to know if its worth the trouble sorting these out? also is there a way to make a pool with sub groups?

There's no need to break it up into chapters. The one pool is sufficient.
