Thanks Joe,

I'm used to contributors who are perfectly willing to share information, but are less keen on those same words being reused in an online site, hence I try to be careful when I intent to forward information that way. Also, some people will answer me, assuming I have vast knowledge, while it's usually the lack of such knowledge that is the reason for me asking. Asking for permission gives them another opportunity to check that their words can be understood by the uninitiated.
