Monster Truck on Francis St, D8, are open to this kind of thing aswell, there's been a few (film only) photographic exhibitions there. La Cathedral, down the road from it is another fantastic space. Loads of soft natural light.
One of my dislikes about exhibiting in DCC is everything has to be so uniform - Some people print big, some people print small - some people don't want black mounts, and hell, some people might even like a tacky frame
As regards the name, 'APUG Ireland Region Annual Exhibition 2009' works well as a subtitle, but something a bit more bold and stand-outish is great for attention grabbing, even a single word that could cover everything...
