In the interests of completeness, my current armies are as follows:

40k:

HUGE Csm army
Large eldar army
Small deamon army (primarily allies)
Large Grey Knights army
Still boxed Necron army

Fantasy:
Vampires army
Still boxed Avatars of War Chaos Army

However, one of my favourite past-times is scouring forums for trades so the above lists are liable to change at any moment!
