How can I arbitrarily execute a rule from the UI to test a login togobban workflow using selenium?
I ended up solving this with rules by making a new rule.

Event- "User has logged in"

Conditions- "User has roles" -> The role of the "unverified user" (set on the 
logintoboggan configuration screen)

Actions- "Show a message on the site"

Message text:

&lt;a href="[account:validate-url]"&gt;validate your account&lt;/a&gt;


This will present a message to unverified users when they log in allowing them to verify their accounts.  Of course this has to be disabled for production, but it allows one to test validation workflows in Selenium.
