If I did offend (and I hope i didn't) then I am sorry. Please remember that when some of us answer we are also answering it with the thoughts that SOMEONE out there (usually a nonregistered guest just 'peeking' at things) will take what we say as ABSOLUTE FACT even if we clearly state it is our OPINION! Please remember that as is in this case....I am CERTAIN there are ways to check the line.... BUT I know I don't know specifically so I will advocate the SAFEST way to approach the situation (don't even think of checking) so that the most causual observer will think---I'd be insane for even thinking it! Personally I do think it is an excellent topic. I am interested in the answers. Don't know if I'd try any unless I had ABSOLUTELY NO OTHER WAY....I've seen the damage done by them first hand.
