Welcome!
It is easy to create a Alankomaat Foorumi rss-feed on your own.
Use these valid parameters, after this url, http://www.finlandsite.nl/foorumi/syndication.php (this file runs all the topics, complete content):
chars=[number] - number of characters per post, HTML and BBCode tags get stripped: syndication.php?chars=200
count=[number] - number of most recent posts: syndication.php?count=3
fid=[number,numberX] - forum id, multiple id's separated by a comma: syndication.php?fid=32,50
t=1 - first post of topics only: syndication.php?t=1
t=2 - last post of topics only: syndication.php?t=2
type=atom - Atom format: syndication.php?type=atom
You can also combine parameters: syndication.php?type=atom&count=3
The default without parameters results in: RSS format and all contents of the 10 most recent posts of all forums.
