That's something very common in SL. People come and go, mostly because a lot of them use alts, so one day they get bored of the alt and just stop using, or just RL needs their attention. So you only can remember the good times you had with that person.
For example, I wonder what happened to Tiffani, a promising new star in the industry. She had the looks and attitude to become a legend, but she stopped logging since last year. I wonder what happened to her...
Since #PrimFeed has become the new main social platform for most of citizens of SL, I left this space without updates. I think I'll use to repost old pics if somebody here wants to enjoy it.
