The ISZ has decided to cease hosting Nraas Industries according to Twallan, and he will now be supporting and hosting his mods on a new site. All mods will be moving to Nraas.Wikispaces.com, where Twallan will continue his support for newer mods.
It would behoove you to check out Twallan’s forum post at Nraas regarding saving and backing up any obsolete mods. There is no set date of closing at this time.
Thanks to Rincon Del Simmer & Capital Sims for the heads up.
