Here's my plan; as active members in ESO we'd like a couple hundred more Family members. How about on March 17th we give away “Blue Food” to random players.
We'll need to pre-craft health/stam and health/magicka food of levels 10 through 45. On the 17th we'll have “recruiters” stationed in Stonefalls, Deeshan, Shadowfen, and Eastmarch. These recruiters will periodically spam:
“Gaiscioch Guild is giving away blue food, whisper for delivery.”
When contacted, find out their level and whether they need magicka or stamina based boosting food. Then grab the needed food from the Guild Bank and mail it with the message:
“Presented to you by the friendly Gaiscioch Family, go to GSCH.info for more info.”
Fairly simple, might be effective, won't hurt to try. Please reply with willingness to recruit, craft, or donate provisioning mats to Guild Bank.
