SL gives you a warm welcome
When I joined Second Life somewhere in 2006 there was a basic introduction island - a tutorial. After you'd mastered the basics of SL (walking, flying, teleportation and changing your appearance) you were set loose in the wild wild world. At that time the point of entry was the sim called Luna, just south of the urban sims Grigano, Barcola and Sistiana (collectively known as Nova Albion).
Nowadays there's a new version of baby-island and probably a new 'drop-zone', but Luna wasn't the first drop-zone. Before Luna there was Ahern and the adjacent sims. They can easily be spotted, east of Nova Albion on the mainland. On the map a large X on the border of 4 sims marks the old point of entry. This point of entry reminds me somewhat of the London Market Gardens. Ahern is beyond the meet and greet now and has degraded to a pick-up zone and looney-showcase. If you avoid the looney days, SL might just give you a warm welcome here.
