I'm mixed, I'd rather try to avoid having users that are sending threads to the forum have to do alot extra, or remember a password.
Heck, I have users now that have to reset their passwords weekly because they can't remember them
I'd love to hear from others on if they think that this would be nessecary.
Or if anyone else has any alternate ideas
Secondly, if you have a "competitor" on a shared server spamming your board... I'd really wonder why your host isn't doing something about that, as the end result would be them crippling their servers
I understand your not trying to be difficult.
I just don't find the system your suggesting to be feasible, and would like to find an alternative
