Hi Ivolucien and welcome to MediaWiki.org!
Thank you for your comments regarding SocialProfile extension. However, I'm sure that more people might see them and comment on them if you'd post them on the extension's current talk page rather than on an archived talk page — after all, they're supposed to be archived. ;-)
- I appreciate the note Sayuri. I wanted to write those comments in context, but I suppose I should have simply quoted the archived conversation. - Ivolucien 02:38, 10 August 2008 (UTC)
Now, adding a switch like $wgUserProfileDisplay['levels'] to toggle the display of User Levels in social profile pages would be totally trivial - but also pointless, since User Levels do not show up on user profile pages unless $wgUserLevels is set.
Let's face it — SocialProfile extension was not meant to be very modular in the first place. Many of the current stuff depend on each other, and UserLevels is referenced in differents points of the source code because different actions can earn you social points etc.
However, while I can't do miracles, I'd certainly like to hear if you've got suggestions regarding the extension. :-) Ideally, you could disable i.e. UserRelationship and UserBoard with a few settings in LocalSettings.php, but eliminating the dependencies is not an easy task.
