A general guideline for all posts, and especially for new threads is: No clicks should be required to understand the post This applies mostly to three things: Links Videos Attachments Links The reader should not have to click on a link in order to understand what the post is about. If you link to something then: Describe what is in the link, and why it is relevant to the thread topic. Quote relevant excerpts using EX tags, Include images and screen-grabs from the link. Links themselves are not content, they are references. Videos The reader should not have to watch the video in order to understand what is in it. Describe what the video is about, explain how it is relevant. Use time codes to precisely locate the relevant portions of the video (preferably wth the time encoded in a link). Provide a transcript of any important speech or text in the video. Use annotated screen grabs to convey the content. If you can, create an animated looping GIF (under 2MB) of the most relevant part. Attachments Image attachments should be inserted into the post, not attached at the end where the reader has to click on them. Attachments such as PDF files should be treated as links, with an explanation of what the file contains, and if possible quote the relevant text and/or images. Use common sense. The degree to which the above applies will vary with the context. But if you are unsure, then side with "No Click".
