I realise that people have already been posting them, by people I mean characters with businesses, but as my character was wandering around NLM today I thought it might be a cool idea to have a classifieds/ad desk at NLM where people with businesses who want advertisements. Maybe not those as slick as the ones that are on the NLM for the places like Carnal and the Red Canary, just ordinary text ones. They could pay for the advertisements with a terminal, it would probably easier than having an NPC there and then put it in a special forum for advertisements. Sort of like a NLM yellow pages.
On another note, it would be kind of cool to see more of the advertisements that are there for the npc type businesses like Neo-Trans and stuff. Those are awesome. I love them. They add such realism to using the quickterm site.
