The XenForo software package provides a Trophies feature and on-line Xenforo-related comments generally treat this with derision.
There is also a Badges feature (mentioned here)
https://xenforo.com/community/resources/badges.7367/
but that does not appear to be fully integrated for this forum.
As a significant selling-point of the XenForo package is that it is highly customisable, the current Trophies criteria could be changed or Trophies/Badges probably could be completely suppressed.
There will be certain things that forum participants will need - like the ability to post and reply to postings easily and effectively - and this forum has that. Then there will be ‘unnecessary’ features that can be provided and that some people will enjoy and others loathe. For instance, the Facebook liking/friending/unfriending ethos may be attractive to some, but not to others. It’s possibly useful to me to know that you first registered to the Practical Caravan forum in 2005 and that you’ve posted over 6000 times since then, but I’ve no interest in how many ‘likes’ you are clocking up, nor what your Trophies points-score is. On the other hand, ‘likes’ and Trophies data are harmless enough.
It’s up to forum users to be proactive over what the Practical Caravan/Motorhome forum’s XenForo software provides. Before the ‘old’ forums were migrated, better facilities to attach images to postings and a private-messaging capability were asked for and these are now present. But if forum users generally REALLY dislike some of the ‘extras’ that XenForo offers, (like the Trophies thing) they should say so.
