Sorry I'm so slow to respond to this. It's been ages since someone last applied for an account, so the forum isn't nearly as active as it used to be.
Nice photos! You've clearly been at it a while!
That said, I'd like to ask what plans or needs you have that make xepher.net a better fit for your site than any of the services more directly dedicated to art/photography. E.g. what're you planning/hoping to do that you couldn't more easily do on sites like flickr, photobucket, deviantart, or even wordpress.org itself?
Secondly, the services here are pretty low level. You get file and shell access, but you'd have to install and maintain wordpress (and anything else you use) on your own. Do you feel you have the technical skill to be able to do that?
