Ok weekend- the best time for all parties involved to get together and be on at the same time, now i'm horrid with time zones so i usually go by easter standard time myself
As for rules- well i'll leave that up to everyone involved, i'm an extremely flexable DM if i would do it then my players can do it, though i tend to slice out the skills part and think along the lines of if i wouldnt be able to do that then my character cant, the other thing i slice out is money for starting characters, i mean Its not like a 1st level char is going to be able to afford everything they might need for an adventure or journey, but i do assign money from fights and exp as well
also, if it's in a d&d book it's fair game for a character unless it cannot communicate with others or is so advertly powerful that it would wipe a city off its setting map.
Now i've started mixing D20 with D&D because i love mutants and other odd things and i also love the feel magic and medieval settings give things, so if you've never played D20 or you have and liked it i use it to some extent when i DM, if you need to know what books i have in case you are looking for something specific i have: PH 3.5, DMG 3.0, MM 3.0/3.5/2/3/4/and 5, as well as the feind folio, the monsters of faerun book, and the D20 future book along with the D20 modern book on a disk i can use eberron as well
