Expiry / strength tags

The tag system has been upgraded to "expiry / strength tags" to record member behavior more precisely:

Expiry tags: removed automatically a set time after being applied, great for recording time-sensitive behavior such as interests and campaigns

Strength tags: the number of times a tag is applied adds up to the tag strength, great for recording behavior that may happen repeatedly

By making good use of expiry / strength tags, brands can precisely distinguish types of member behavior or create more flexible marketing campaigns.
