Explicit contest rules

Modes:
Valid modes used in the contest should be called out explicitly in the rules.
Dupe example: "Work stations on 3 modes per band: PH, CW and Digital (all non-CW)".
Mult ex: "Multipliers are counties per mode: PH, CW and Digital".
Most sponsors use `RY` for all non-CW digital modes. Ex: "All non-CW digital modes are `RY` in Cabrillo".

Multipliers:
Mults must be detailed in the rules as well. "Multipliers are States, Canadian Provinces and DXCC countries" is so generic that authors of logging and log scoring software will scratch their heads. If the rules are explicit, then chances are that more submitted logs will be formatted the way you want them.
Ex: "Multipliers are US States (50), Canadian Provinces (14) and DXCC countries. US, Canada, KL7 and KH6 do not also count as DXCC multipliers. Canadian Province mults are: AB – Alberta (VE6), BC – British Columbia (VE7), LB - Labrador (VO2), MB - Manitoba (VE4), NB – New Brunswick (VE1, 9), NF – Newfoundland (VO1), NS - Nova Scotia (VE1), NT - Northwest Territories (VE8), NU - Nunavut (VYĜ), ON – Ontario (VE3), PE - Prince Edward Island (VY2), QC - Quebec (VE2), SK - Saskatchewan (VE5) and YT - Yukon Territory (VY1)".
The Canadian mults and abbreviations could be listed as a separate appendix. The same with the US state abbreviations.

Log submissions:
Log submission details about log format, classification and submission will increase the chances that the logs are the way you want them. If the log submission format is Cabrillo, be specific about the format by publishing a Cabrillo template so logging software authors can write the correct output file.
