"Unfortunately the majority of contributors to the science subjects drifted away reasonably soon after we moved here. Those of us left either don't know enough in depth, don't have the time, or are discouraged by the lack of interest."
I can well understand that EFFT. The 'format' for 'posting' here is so different to what posters were comfortable with at the C4 Eve site. I've recently been 'copy-pasting' into 'MS Notepad' for post construction, then copy-pasting into 'Open Office' 'Writer' for uploading onto a site. It works for 'Word Press' sites and may well work for this site, we'll see if this post works. However, 'Word Pro' (my preference for a word processor) seemed unusable for me and 'Notepad' is restrictive on 'character diversity'. That does seem to be the major 'downside' to posting here. 
If you 'know your stuff', you need to be able to 'explain it' properly. 
"I always enjoyed reading 'your' debates on C4 around various science subjects."
Although I'm flattered by this response (my comments were 'rarely' 'liked'), are you trying to 'enlist'?
