:) FIrst: The best way to improve your profiles is asking! And you did!!! Thank you so much.
As I started at WikiTree, and I am from the Netherlands - (so I am sure I will make spelling and language mistakes too :) ) - I was asked the first weeks at WikiTree to join the Dutch_Roots_Project. As I was new I hesitated. I m just a hobby genealogist. But I jumped in the Project and learned so much. Mostly because the leader of the Dutch_Roots_Project is such a nice and patient lady.
This is not about me. Just pointing that if you re interests are somewhere close to a Project feel free to join. And keep asking!!!
Now what you would like to add to which profile. We can help you to make references, how to add images. We can make examples to one of your profiles if you like so you can see at your edit page how it's done.
I even think there are several example profiles. If you click on the edit page of a profile you like you can see how things are added like images or references.
Please share a profile you like some help on and I am sure many will love to help you. There are many friendly people here to help everyone.
Kind Regards from the dark (bedtime) Netherlands.
