After signing up for their newsletter, I got an email today that let me know they are now open for translations.
If you register on their community site it gives you the option to select which languages you know and at what proficiency you know them. It also gives you the option to add a new language if the one you want is not there.
For myself, I selected English-US and I added Esperanto, as well as Toki Pona. I think if we get many people adding these languages they will be more likely to add them to the possible translations.
I don't have much experience in translating Toki Pona for the internet and computers, but I think it will be fun to try this
