It does appear Farcaster has done a
few mods to handle Social Group Events and the like. Hrm, actually, I should look into that more. vB has only implemented the Social Group aspect into it's core in the last couple of years, so the functionality is meant to be pretty basic at this point. Be interesting to see what they might add down the road.
It's not terribly hard to install modifications, however, it depends on the modification. But if you know the basics, there are few, if any, products here that require in depth editing. The vast majority are upload this, import that, put this line of code in this part of your template. Check the link in my signature to "How to Install Mods" for Beginners. That pretty much breaks down everything you would need to know and clarifies a few things that we call "modifications" but that really aren't. These days, there's not a lot that will actually modify code, and modifications can be globally disabled a couple of different ways.
