What does the titles mean?

[AmericanMary]

Under our names when we post there is a little title. At first mine said something I forgot, and then "experienced" and now "specialist"

Who changes these? It's it an automated thing? What do they mean?

Some pls help me understand

It seems to me that it is your level of the platform establishes as you interact with the community by posting threads. I tried to change it but it automatically returned me to the one I have.

Number of posts I imagine.

It has to do with your level of engagement on this forum. These types of titles are common on forums in general. They change automatically depending on the amount of threads and posts that you've made.

It looks like you can set that title in the account settings.
Edit: You can, but it doesn't seem to be reflected in the posts.
