Is that a rhetorical question?
Well in such cases you just create your own room and wait a little until someone decides to join it

A little bit! I wasn't sure if it permeated into the Internet, though!
Well, the other sad thing of course is setting up a game and no one joins. Lonely dork boy at his cake and punch party, you know. And futile if everyone on the server is part of another game(s) that I was booted from. So sad, especially when there's only five other people playing in the first place.
Oh well, someday I will gain freeware Worms-clone acceptance. Someday...

Oh, well...Don't be sad btw You'll get more "clients", if you give your room some kind of cool name that'll attract people's attention. Simple psychology.

Hmmm. Something like these maybe?

'Free Money'
'Hot Geek Girls'
'Good But Not So Good That I Will Win'

"FREE BEER!!!" works always

Yeh, something funny. First you can try of course to invite some players from your own country. For example "Room for dudes from XYZ" or "XYZ action" (XYZ = name of the country and the appropraite adjective like Brazil -> Brazilian etc.). I'm sure there are guys from your country around here.
