Hi swordy,

Not a stupid question at all!  I also only 
collect from one series and debated how to 
display my 2-character cels for a long time.  I 
finally decided to put the cel in the gallery 
twice, once under each character.  If the cel has 
3 or more characters, it then goes under my group 
section (with rare exceptions).  My main 
reasoning was because I have a lot of cels with 2 
characters and I didn't want my group section to 
be huge.  Also, 2-character cels just don't seem 
like group cels to me.

Hope this helps,
