how can I make a web group?

[gfp]

Hi,

I want e.g. news from a website:
https://musescore.org/en/forum/4492

How can I create that?

1.
If I do a "G w"
it asks me for a search pattern
I don´t know what to enter.

2.
If I do a "G m"
select method for new group:
nnweb:https://musescore.org/en/forum/4492
then I get a new group
but in opening it it says:
couldn´t activate group nnweb:Musescore: No matching articles

what is my mistake?

3.
What else can I do to create a group from a website
which has no rss feed?

thanks

Gottfried
