Appreciate it -- thanks :)

well one way it could be done very easily and safely is this:
i could add a profile field to each users profile, where they could write custom BBC code (which would include the ability to use url links),
and then the forum would display that text at the top (bottom) of the forum pages FOR THAT USER ONLY.

so basically a way of letting users add their own custom links/text. near the built-in forum menu -- that would affect them only.

Yes, this is the sort of thing I had in mind -- but may be it's premature.  Was curious about the difficulty of implementing such a thing and what the computational costs might end up being.  Of course, this is all very vague :)

of course this is really not any different than users using their own greasemonkey scripts, just a bit easier -- but much less flexible.

It seems possible that for the share buttons (some are iframes?) by the time Greasemonkey gets to remove the related nodes, it may be "too late" in the sense that one's info might have leaked to certain sites.  Not certain -- may be someone else knows better?
