For reference, the reason it's helpful to name your closest GW is because, if you fancied meeting someone for a game, a Games Workshop hobby store is a safe, neutral location given that this is the Web, where there's no guarantee that anyone is who they say they are and that many INQ players are minors.
Whether you regularly frequent your nearest store is, in this context, irrelevant.
That said, if you are a member of a GCN club then that would be an equally good meeting place.
