I migrated my personal homebrew website to WordPress and have been running it on my own server. I'd like to move it (and its domain) to wordpress.com. I have a large number of 301 redirects in my .htaccess file, pointing URLs from my old site to their current locations in my WordPress site (and other places I've moved things, like Flickr), and I'd like to leave them in place for a time while Google, et al. catch up.
Is it possible to edit the .htaccess file for a wp.com-hosted domain, or is there another solution for this problem?
I'm sorry if this is already covered somewhere, I wasn't able to finding it in the wp.com documentation or forums.
