I've registered the #ragnarokbattle channel in both xelium.net and deltaanime.net. support for those two networks is at network.xelium.net and deltaanime.net. Since I wasn't sure which one people were going to connect to, I've registered both.
note: I won't be very active (Pandasu on Xelium, hikaritenchi on DaNET) today or tomorrow.
IRC help is available at irchelp.org for new users.
so I don't know if I'm overstepping the lines of authority on the forums by doing this, but I only suggested this as an alternative to the flashchat. However, I think that if the flashchat has the problem of not enough users, the IRC chat will have the same issue. Also, there's a small learning curve associated with nominal IRC usage, which may also turn people off. At any rate, the channels are there for you guys to play around with.
For people without IRC clients, xelium.net has a java irc client at
http://network.xelium.net/chat.phpAfter selecting a nickname, type "/join #ragnarokbattle" without the quotes to join the channel.
On DaNET, their non-java client is at
http://chat.deltaanime.net/choose a nickname and in the #channel field, type in "#ragnarokbattle" without the quotes to join.
For Windows clients, mIRC.com has the most popular windows client I've ever seen.
Mac users can use snak 5.x, i think.
*nix has *I think* ircII as a client.
I'm a windows guy, so I'm not sure. I use mozilla's chatzilla myself, but there's no real good reason to prefer chatzilla over mIRC.
