You've got a point sawlight, but a proposal could still be put together and submitted. I think if it makes sense, improves things here and doesn't make the moderator's lives any harder than they are right now it would be considered.
The problem is how to get there.
Well, as Baditude said, I was also involved in the layout for safe sub ohm vaping, and have yet to see anything come of it either. I'm not sure how many of us were all involved, but I'm sure a lot of time went into it altogether. I was happy to see a stance taken then, so I know it's something that is a concern to them. I was honestly hoping one or more would have jumped in on my last thread on this topic in the vets area just to throw some insight in. So, well, I have no idea!
