I'm a premium member, own land, pay a good $ per month. Although I own land, I want a Linden house, too. I'm also seeing the 'sold out' sign, and have seen it several times over the course of a week.
When I am able to get a Linden home, if I don't like it, I look at the map and mosey around to see what else is available.
I've come across a slew of homes that are owned by Linden that I would love to take for my Linden home. Instead, they assign one to me, I go look at it, and it's in a horrid location, nothing to see but someone elses house right up against mine.
Why doesn't Linden Lab set it up so if you find a home you like, you can right click and rent it? Why do they have to assign the homes? Why can't we browse the neighborhoods and pick out the one we want?
