I am now a signed-up member of:

• delicious
• digg
• diigo
• propeller 

I've played around with a few plugs, but I'm feeling my way through the dark.I don't really know how to make the most of these sites. Nor have I been able to find a comprehensive guide to help me tap into their unquestionable value.

I've posted on the forum a couple of times in connection with social bookmarking, but have barely had any response.

 Think I might try again.
