Every user has a Reputation score. When they post clear and useful questions or answers, other users can vote their score up or down. To view a user's rep score, click on their User Name or Icon.

Voting a question or answer up adds 5 points to their Reputation score.
Voting it down causes them to lose 2 points.
If a post is removed for violating the rules, they lose 20 points.

The rules are:
* You cannot post identifying information (Email, Name, Address, Telephone)
* You cannot use Ehelp to promote products or web sites.
* You cannot attack or abuse other members.
* Any other posts judged to be outside the intended purpose of exchanging useful information may be removed.
