If you don’t have anybody going to your site just yet, I’d go ahea and put htem up. HOnestly, who’s going to find your site if you don’t want it to be found.
Now, I dunno about SEO and having your site be up longer and all that, but if that’s true, I’d go ahead and get your stuff up now.
YOu can always edit it later and just because your site isn’t yet ready for launch doesn’t mean that you can’t put some pages up.
