I feel like I can't possibly heap enough caveats and abdications of responsibility on this suggestion, but Reddit is like the Grand Central Station of forums.
Anyone can start a forum (called a subreddit) for anything and be the moderator of it. There are several vaping forums. A good place to start is:
Vaping • r/Vaping Other prominent subreddits for vaping are listed in the sidebar.
I personally subscribe to twelve subreddits. (That means when I open Reddit, I see the latest posts from those forums.) Mine are: Arduino (a brand of single-board computers), Conlangs (constructed languages), DIY, Electronics, Fantasywriters, Jokes, Roku (a device for streaming tv), Timetravel, Woodworking, Worldbuilding and some region-specific ones, so you can see what a variety is available.
Now here's where the caveats come in: the basic rule of Reddit is "keep it legal." That's about it.
Whoever creates a subreddit determines what type of moderation it has. Some are very strict: one toe out of line, and you're permanently banned. Some are sort of strict: no banter, just the topic at hand.
Some subreddits are quite free-wheeling as long as you're not using bad language, attacking others, or posting inappropriate pictures.
Some virtually demand raunchy posts: if you don't use very foul language, engage in flame wars, and post filthy pics, you'll be totally ignored.
All I can say is I was on Usenet for more than a decade, so I consider myself fairly jaded when it comes to Internet postings, but there are many subreddits I would never consider visiting.
i never been part of something like this and don't know what to search for when looking for some other forum.
