Newbie help please

I'd like to add sites that I know in this bit of Central Portugal but I don't see how to add a new site, only how to add posts to existing sites. Lots of dolmens, stones and 'anthropomorphic graves' around here, and if I get them listed I hope to meet others who enjoy a bit of rock-bothering. Obrigada.

Hello Granny Debs, welcome to The Modern Antiquarian!
To add a new site, you find the main page for the region you wish to add a site to, e.g. for Alentejo:

https://www.themodernantiquarian.com/site/13470/alentejo

From here, click the 'Add content' button and then 'Add a site'.

Once submitted, the site will then sit for approval by TMA Eds. Please provide evidence for the site existing with your submission, as that helps achieve much speedier approval.

Thanks and best wishes,
TMA Ed.
