Welcome to the British Expat forum.
Sure, we welcome it when people tell us about events and what's happening so you can give us details about what, where and when. However, no website links, please.
If you want to promote a website, then you'd need to take a small ad (£5) because, as you noticed, we don't allow advertising or promotions except in the dedicated advertising areas.
It sounds like a fun project. If you send me an article about it - and maybe a photo? - I can publish it and give you a link in the "about the author" box. If you did that, we'd also mention it in our opt-in email newsletter.
Hope this helps, and good luck with your project.
