I think i'll stick with the 10-15 on my box thanks
If you want to earn money from Hosting LFS servers, I would suggest you come up with a standard SLA (Service Level agreeement) And detailed information on what comes with the server, Ie what if an Admin wants to Mod thier Server (such as the STCC run quite complex Databasing and custom software running on the server).
Also giving away the odd free server to something you consider a good cause wouldn't hurt your Popularity.
UKCT arent in this to make money, so we only offer Free Servers to something we find interesting, or that we as a group would like to support We dont sell them.. Although we have been approached in the past, Purely because of the support we have offered the community.
