If you’re going to do much work on the web besides typical posting, etc. on your blog, you’re going to need a good FTP program.
My suggestion is SmartFTP … pretty neat program. It remembers you addresses, passwords, etc. And you can have multiple tabs and thus sites up.
We recommend FileZilla (http://filezilla.sourceforge.net/) from the makers of FireFox etc. We’ve found it to be the best FTP client and it’s super fast as it will transfer multiple files at one.
