Why wouldn’t you want real names to be allowed?
Personally, I think the other Torre forum has the best approach - you pay a nominally annual subscription by PayPal . This ensures that if you want to have multiple personalities then you have to go to the trouble of setting-up multiple PayPal accounts - each of which need to be linked to different credit/debit cards and email addresses.
In other ways the other Torre forum has totally the wrong approach. I recieved scolding emails from the owner for mentioning a Facebook group and for making a public suggestion about how to improve one aspect of the forum (aparently I should have made the suggestion by PM to the owner or mods). Eventually I told them that if they weren’t happy they should terminate my membership, which they did.
I don’t think there’s really a big enough gap in the market to justify setting-up a new forum. With all the Facebook groups and forums like Talk Quesada and the Costa Blanca Forum, plus the other Torre one, I think the market is pretty much saturated.
