Hi
Actually I think it is a fairly good idea with a couple of refinements, such as you suggested, where each Post was started with each COUNTY...
Then ONLY if you are in that county do you reply to that Particular post, adding sellers of Nitrous etc...you could also add people like me who have a big bottle but are not retailers but are willing to fill with a little notice to help out other WON users...
Thats assuming Trev would approve that part, as possibly the retailers may not like it...
Once there are a few posts , then a mod (like me lol) could delete the earlier ones and should be able to get them down to one Post per county...
All the best Brett
