People signing up (that is, joining) would have to check a box indicating that they agree to the terms and conditions. These might include:
- posting in the correct forum
providing a profile
understanding that responses are voluntary (there is no "urgent" here)
"shouting" (posting in all upper case) is offensive
posting solutions when found
avoiding language constructs that make life difficult for those whose first language is not English - particularly SMS-style shortcuts (u no hu u r)
