X-Git-Url: https://git.mxchange.org/?a=commitdiff_plain;h=223795a2e430544e9702b1a6a5680fa4b8dfbb76;p=quix0rs-gnu-social.git

Add config option for RequireValidatedEmail plugin to skip the check for folks with a trusted OpenID association.
Also added an event that other plugins or local config can use to override the checks.

+You can also exclude the validation checks from OpenID accounts
+connected to a trusted provider, by providing a list of regular
+expressions to match their provider URLs.

+For example, to trust WikiHow and Wikipedia users:

 Todo:
 * add a more visible indicator that validation is still outstanding
