Aspire Isle

Just a quick question: I've heard various bloggers mention how amazing and beautiful the new Aspire! sim is. So I thought I'd go check it out. But I can't tp to it. It seems they've restricted access at this point. I'm just curious... does it take a special invite to gain entry? Or did they once have it open to all and recently restrict access? Or was it just poor me that couldn't get there? I even looked at it on the map, tp'd to the nearest sim thinking I could fly to it. Wrong! There are no connecting sims, so no flying in. (Yes, I was determined) Just being curious because I can't wait to see it. ;)
