I’m going to try to explain how building the URL for this works. I hope it makes sense!

So the following URL (in markdown) creates this pre-filled PM to myself.

[**Click here to request help with Community Structure**](http://www.reddit.com/message/compose?to=RuddersUp&subject=REQUEST: Community Structure&message=Hello please put an x in the box where you would like assistance [] Help developing clear and concise rules [] Understanding Reddit Content Guidelines [] Automod or Crowd Control Configuration [] Creating a clear description for your community [] Developing a Community FAQ [] Establishing post and user flair [] Updating sidebar with useful content and information I will get back to you within 48 hours!)

Breaking down the above, it fits the following format:

http://www.reddit.com/message/compose?to={dest}&subject={subj}&message={message}

{dest} = user (name only) or subreddit (/r/subreddit_name)

In the example above, it sends a message to myself, so RuddersUp is the {dest}. If you wanted to send it to the mods of this subreddit, you would replace RuddersUp with /r/Reddit_Canada.

http://www.reddit.com/message/compose?to=/r/Reddit_Canada&subject={subj}&message={message}

{subj} and {message} fields are similar text fields, with the {subj} having a character limit. They use the following formatting:

• Spaces are replaced by
• New Lines/Carriage Returns are represented by

What I found helpful was to use a word processor’s find a replace tool to replace all the spaces, and then manually put in the new lines.
