You might also bear in mind this is a big step to take. There is a difference between the rights of Members and Suppliers on ECF - once you become a Supplier there are several places you can't post, for example. Instead of being one of the community you become a dealer, and that is a different situation. Also, many ecig traders fail, due to not being strong marketers, or because their imports are seized due to government's attempts to protect tobacco tax revenue (this being a global situation currently).
Some eventually revert back to member as it's not worth the hassle. It's not a step to be taken lightly. It works out best if you already know you are a good salesperson, and also have some solid sources of supply.
