What are some of your favorite IPB MODs and what kind of functionality do they provide?

I try to keep mine to a minimum but so far I'm enjoying a few of them, some of which aren't live on this site yet

 

• Welcome thread for new members
  
• Points & Store System
  
• MinervaSEO (Though this still seems really buggy to me)
  
• Sitemap generator
  

I have another favorite installed, but I can't think of its name atm and am to lazy to go check it out :D

I don't like to overload my site with mods, but usually the simple blog system, member teams, and sliding log in panel are the general ones I use.

I used to like the ibProArcade and ibProBattle mods, but they never really showed any good activity on the site.

The testimonial modification for IPB is quite sweet!
