To detail on the "garbage" part; apparently the colon is, while
unconventional, a legal part of newsgroup names, to be precluded once the
USEFOR draft becomes a standards-track RFC. The latest, albeit expired,
USEFOR draft restricts newsgroup names to alphanumerical characters,
underscore, plus and minus, but it's just a draft...
