I've mainly been standing by watching the thread go and seeing if there is anything I can input.. and finally there is! I would recommend making a whole new forum topic about this event, the comments here are getting clustered and I'm not sure about the validity of the original post, does it reflect rule changes implemented since then?
Anyway, If I were you I would remake the topic entirely. Make sure it is formatted and has a way to sign up included (assuming this is an open tournament), I would recommend making a google form for signing up, I can assist there if necessary, that way all your replies etc are instantly put into a neat little spreadsheet, to make your post clearer I would also recommend writing up a little rulebook (once again google docs is nice, due to the easiness of sharing files) with EVERY rule, so that the main post contains the basics and essentials (dates, maps etc.) but there is also a place to find situational rules (replacements, rescheduling dates etc.)
Just my personal opinion!
Cya in the skies!
