So buy refusing solo diving a forum because a few people are on about "because its dangerous" then yes we should also ban any talk on technical diving, mixed gas, rebreathers and any deep stuff, after all, the statistics are clear on a higher % of incidents involving this type of diving compared to <30m "fun" dives.
A solo diving forum would be able to discuss equipment, techniques and methods to improve safety in much the same way the DIR forum claims to be all about the same thing.
Some people dislike solo diving and choose never to do it, thats fine and their decision. Some people dive solo often, are aware of the risks and do their best to minimise it, again thats fine, its their decision. Why not give them somewhere to talk about it ?
The quote about beginners rushing off to jump into the nearest lake solo because they read it on a message board is crazy - do these same people jump in armed with mixed gases, doing 60 mins of deco or on CCRs because they read it on a board too? No they dont. It wont influence them.
