Thanks guys - I may PM some more questions if that is OK - this might be more technical that other posters want to read. I'm a real chemistry dodo.... You guys are great! :bowing:
Sorry - I had PM'd Happychem this afternoon, since he was the last poster - I just assumed since this was so technical and therefore potentially not of much interest to people (just me asking questions and I felt like I was begging)..... I'd hate to waste people's time w/ my ignorance. I feel like I did that often as a newbie.... I really appreciate the help and will try to not to PM again unless I've been a complete dodo - and am too ashamed to post.
Cheers,
IL
