Anyone have a suggestion for a non-gender specific pronoun?

The more we interact online the more important this becomes. I hesitate to refer to my fellow Jellies as he or she if I don’t actually know their gender and I’m tired of writing out he or she or (s)he. English is long overdue for a few new pronouns here.

We’ll need something for he/she, him/her and his/hers but there are other linguistic gender imbalances we can tackle here too if you wish.
