Hah, no worries. I was thinking that YA was the only e-mail sub they'd accept, but I wasn't sure. So your post was helpful.
I will move this agency to the bottom of the list with the other non e-mail agents and query them after I have worked my way through the agents who do accept e-mail.
I guess I feel that I want an agent who has joined the 21st Century repping me in the 21st Century.
I can understand that snail mail subs are a hassle and cost a bit of money, but in RCW's case I think it is worth doing.
My feeling is that it is not a refusal to join the modern world but rather an additional filter to try and stop the hordes of copy-and-paste subs and keep to people who are serious enough about their work to invest in doing things the old fashioned way.
They have such an amazing list of authors that I find it a pleasant surprise that they are accepting submissions at all, really.
I say submit; they are a top agency. If you submit to them last and get an offer - only to have to turn them down as you accepted from a less prestigious agency who accepted email subs, you will probably regret it.
Just my 2cents before I slip back into the shadows of silence
