Hi Njoki
I was hoping you could help with this translation.
(I will send the same request to perijove just in case). I don't think we have anyone who can translate Dutch into Swahili! If you have any questions, I'll be happy to help. It is probably a good idea to put my English translation in the 'remarks' section.
Thanks!

The request is for a presentation at school and it says:


Hello dear classmates and Teacher*,
Today we will tell you something
about Africa and its (her?) languages.
Enjoy the presentation!
