This'll probably take some doing but like.... does anyone even USE skype anymore? And google+ is totally dead. Might make sense to put fields for Twitch, Discord, and I realize i'm probably in the minority on this but mastodon as well would be cool.
Custom Profile Fields
A pronoun field somewhere might be also helpful for people. There are probably scripts for freeform textboxes that let you type whatever? There used to be for vBulletin at least.
A pronoun and a twitch field to replace Google+ and Skype would definitely be ideal.
