I installed this Firefox add-on to make clicking the "Follow" button on external servers slightly less of a pain. You need to set your handle in the preferences. I also checked the no-pop-up option. You still need to click a couple extra times compared to following from your own server (Are you sure? something like that). Works for me. Thanks @rugk !
Images below show screen caps of the preferences and changed dialog.
@kristinmbranson @rugk Sure thing, options are always good. Just saying this in case people weren't aware and didn't want to use a plugin. :)
