Re: 1st line of the first post in a topic?
You mean you want the first X characters or words from a first post?
This is possible. I am playing with this myself so users of my bbPortal plugin can use a read more button on the portal if they want to. It wil count the first 100 words and then ad a read more link.
Think this is something you want (without the read more link). This can be done with a plugin and a new function. I haven’t got something working yet else I would post it here…
