You used the WHOIS from Network Solutions. I didn't. That'll teach me. You are absolutely right, "arryn.net" and "arryn.org" are, indeed, available.
However, something even better came up: my BF informed me that an old domain of his, "strife.com" (yes, one of those old now-juicy names you can no longer get; he grabbed it in '96), is still registered. So I had him transfer the reg to the hosting provider we use. "strife.com" is one of those nifty names that can serve as the root domain for all sorts of games and stuff. Assuming I ever tire of Dom 2, strife.com will still be around.
I do wish he'd bothered to tell me this before I had him get "dominions-2.org". Could have saved myself $100. Sigh. Men. Sometimes you just want to choke the living daylights out of them. But they have their uses. At times they can be kinda fun. Occasionally even sweet. Too bad that they're even harder to train than a cat (puppies are easier to train than men -- they are eager to please and don't argue with you). hehe
