Couple of weeks depending on work and other things in life. Like I said, I need to buy a few upgrades for the computer I'm going to try using first. Mainly memory. I'll shop around a little and order it sometime this week. After that it's just a matter of setting all the addons up correctly. I might do that on my laptop beforehand to get it working good and then use the config files to solve block ID conflicts and the like easily. Never setup a server before, so there may also be a learning curve.
I'll let you guys know when its good. Probably keep it invite only.
