Supergroup recruiting drives! (3 mil to spend on a base? whooot!)

20,000 Prestige
Also after the launch of Issue 11, all Supergroups will receive an
additional 20,000 Prestige per Supergroup member, meaning SGs could
acquire up to 3 million Prestige based upon their Supergroup
member****p roster! Actual date will be announced shortly.

So, it behooves all of the SG's to start massively recruiting!

So, can I get your suggestions for best recruiting ideas?

What ideas have worked well for recruiting and retaining SG members?

Anyone in an Sg that has advanced to the point of a defensible base-
raid capable floorplan?

Anyone ever done a base raid?

Ever recruited as an alt and roleplayed the primary as if he was a
different person?

Is it worth the "wow" factor to upgrade your base layout to have
greathalls?
