I have registered on L2Drunken as well.
One thing, the site requires a patch, now i think their patch set ups your host file and maybe uses a modified core.dll, (i am not 100% sure), so be sure to back up your whole Lineage directory if you can. Its 7.5 gig, i know alot of space but just in case.
I'll see you there.
OK, sites a bit all over the place but you register in the forum, then they'll send you a confirmation e-mail and then a 2nd email when the GM's accept you to there server.
Now this update thing, its an exe that will download a bunch of custom files to your lineage dir so be sure you do a back up, one for drunken, one as a spare. The update file is about 1 meg, its just an exe. I saved the exe into my lineage folder to run it, but had probs, so i moved the drunken updater.exe to the lineage/system folder and it ran fine from there (the website isn't to help on running there update). Once you run it, go have a cuppa, its gonna take me about 20-25 minutes, but i always get a slow connection when doing Lineage updating.
