Publicising a niche event in Ireland

[hatgirl]

At every SF/Fantasy/Anime/Comics/Gaming event I go to, people mention really great publicity channels to me. And whenever someone running an event asks for publicity ideas, I can't for the life of me think of anything other than "put up a poster in Forbidden Planet".

So, I hereby dedicate this comment thread to those brilliant ideas. Which is just a classy way of saying "Please help, I have a memory like a sieve."
