supplementX.xmltv.org

Hi all,

with quite a bit of embarrassment I have seen today that 
supplement3.xmltv.org has been neglected quite a bit by me and it seems 
to be horribly outdated.

I have checked the other supplement servers and it seems supplement1 
disallows delving into sub-directories:

curl -v http://supplement1.xmltv.org/tv_grab_eu_epgdata/
*   Trying 207.58.129.220:80...
* Connected to supplement1.xmltv.org (207.58.129.220) port 80 (#0)
 > GET /tv_grab_eu_epgdata/ HTTP/1.1
 > Host: supplement1.xmltv.org
 > User-Agent: curl/7.72.0
 > Accept: */*
 >
* Mark bundle as not supporting multiuse
< HTTP/1.1 403 Forbidden

< Server: Apache
< Content-Length: 292
< Content-Type: text/html; charset=iso-8859-1

and supplement{2,4,5}.xmltv.org seems to be non-existent.

All that being said and the sources now available at github - frankly, I 
do not know how to ensure how "my" supplement copy will be up to date again.

Nick, Robert, others, any way you may help me with some instructions?

Cheers

Carsten
