Theres nothing wrong with taking it in turns to host it. Say I'm busy, someone else can host it, and vise versa.
Its not exactly 24/7 - and I would want my eyes to bleed now would I?
Anyway, so far the custom maps involved are:
haz_justfarfrags1, 2, & 3
kotc (king of the castle)
and perhaps deadcentre.
(Most are TWHL, but a small amount are old time classics or just weird)
I have alot more custom maps but I dont actually no whether I should have them. Should I keep it strictly TWHL?
