Don't look upon these as a strict set of rules and regulations; more of a collection of suggestions on how to post in a friendly manner.
1. When including links to videos please state download size.
2. Do not use CAPS to excess. It is generally considered shouting.
3. Do not use an excessive number of colours.
4. Do not include large inline images in posts, instead add a link.
If you fail to follow these guidelines then it's likely a Traffic Warden will edit your post.
