Basic Question about lists?

Hi Guys

I have a really basic question i was after some help with. Im using Juce to create a Tool for automating some features of ZoomOSC (and OSC enabled version of zoom from, its really cool). One of the things i want to do is make a list of all attendees than can be referenced by the user and saved to a CSV file . This should be really simple but i was wondering what everyones preferred method for dynamic lists in juce is?

i need to be able to add people as the join and then remove them as they leave. both actions are easy to spot and the data is easy to grab i just wondered what the neatest list format is for this in juce?
