This page explains how posts in the ABBUC forum are formatted, how to attach files, how to link or embed images, how to paste images, and how to make links clickable automatically.
Posts are written in Markdown — a lightweight plain-text markup language that is automatically converted into formatted HTML when saved. In the editor, the preview pane on the right shows immediately how the post will look once published.
Basic formatting
Input | Result
**bold**| bold*italic*| italic# Heading| Large heading## Subheading| Medium heading- Item 1- Item 2| Bullet list1. Item 12. Item 2| Numbered list> Quoted text| Blockquote[Link text](https://example.com)| Link text`Code`|Code(inline code)
A new paragraph is created by a blank line. A single line break inside a paragraph is ignored when rendering (the lines are merged into one) — to force a line break without paragraph spacing, end the line with two trailing spaces.
Heading = post title
If a post starts with a line like # My Title, that text is shown as the post title in the header of the post card (for example when starting a new thread). The heading is then no longer shown again inside the post body.
Quotes
> This is what the previous poster wrote.
>
> Second line of the quote.
Quotes can be nested (>> for a quote inside a quote) and are rendered with a distinct background and border.
Code blocks
For multi-line, unformatted code, wrap the block in three backticks:
```
10 PRINT "HELLO"
20 GOTO 10
```
Attaching files
The editor has a file picker below the text area ("Choose file", multiple files can be selected). Selected files are automatically attached when the post is saved and appear below the post under "Anhänge" (attachments) as a list with direct download links. There is no need to reference the file anywhere in the text — every attached file is listed automatically.
Linking / embedding images
To display an image directly inside the post body (rather than just as a downloadable attachment), use Markdown's image syntax:
- If the file was uploaded as an attachment, it can be embedded simply by its filename — the attachment will then both appear inline in the post and still be listed under "Anhänge" below.
- External image URLs (
https://otherdomain.com/image.jpg) only work if they point toabbuc.de(or a subdomain of it). Images and embedded content from other domains are automatically stripped out for security reasons and will not appear in the post. For images hosted elsewhere, always upload the file as an attachment instead of linking to it externally.
Pasting images
In the editor, an image can be pasted directly from the clipboard: copy an image (e.g. a screenshot or from an image viewer) and press Ctrl+V while focused in the editor text area. The image is automatically:
- inserted at the cursor position as
, - shown immediately in the preview,
- uploaded as an attachment when the post is saved.
Multiple pasted images are numbered sequentially (paste_1, paste_2, …).
Automatic links
A plain URL in the text (e.g. https://abbuc.de) is not automatically made clickable — it will initially appear as plain text only.
To make a link clickable automatically, wrap the address in angle brackets:
<https://abbuc.de>
<info@abbuc.de>
which becomes:
https://abbuc.de or, for email addresses, a clickable mailto: link.
To show custom link text instead, use the regular Markdown link syntax:
[ABBUC website](https://abbuc.de)
