@Crazy-Achmet originally funded the Waindigo friends addon and I funded the vbulletin importer for it. The addon was popular but proved to have too many problems/bugs. No one has since created a replacement.
The concept is similar to Facebook:
- Members can send a friendship request.
- If the other party confirms, then the members are listed as friends on their profiles.
- Friends can be subscribed to. (followed & watched)
- Privacy controls allow members to share content with friends only. Addons can extent this.
I know there are people who have the opinion that stock XF followers functionality suffices. But please respect that this is not the case for everyone. So please do not make this thread a discussion about whether or not people should use such an addon.
