There is no problem researching it and discussing it and you did not break the forum rules, BUT you asked who had used it and what the outcome was. Anybody who answered that question would have had their post deleted.
I posted what I did for two reasons.
1. To let the members know that the rules do not permit that type of discussion.
2. To reduce the time I would have to spend deleting posts and sending PM's to members explaining why their posts had been deleted. Also reduces my e-mail inbox size. :B
