I'm trying to create a page that links to another blog site. The themes I'm working with don't seem to allow me to do this. I've tried creating Custom Menus, but if I change my theme these disappear and the 'home' site says it doesn't exist. This is for pencilfirst.wordpress.com and I'm trying to link to the blog findcalistahere.wordpress.com
The blog I need help with is pencilfirst.wordpress.com.
