I like the idea of a welcome basket, or maybe just a box prim.. :matte-motes-wink-tongue:
Hmm, what to put into it that would be universally useful... definitely a notecard of welcome, with some of the general information about what Bay City's theme is, including links to relevant wikis and such, in order to give some idea of how best to "fit" their build in. Maybe a copy of the LDPW textures and stuff too.
It's hard to come up with anything more specific, as we have several different types of businesses, entertainment venues and residents.
As for distribution of this welcome kit, perhaps some sort of team effort for that - if you see someone new to the area, introduce yourself and offer the kit! (Once it's in existence...)
