Hi Tzafrir :)I do remember using Performancing fro Firefox a couple of times for this blog.
I tried Perofrmancing now and it isn't working. So strange isn't it?
My host doesn't block xmlrpc, and they're checking it out right now. I've searched all over and found a Wordpress.Org support thread saying this file should only return 403 messages. I dunno.. 
I'll keep you posted, thanks!
