I'll work on making it easier for you to share topics and individual posts with your friends, but for now here's what you can do.
At top of every page you'll see this button:

Clicking the button sends the current page location -- as shown in your browser address bar -- to the ADD THIS social-sharing service where you can post the link on your favorite social network sites.
The trick is managing the address that gets sent to ADD THIS.
Before you click the button, decide if you wish to link to the entire topic or an individual post within that topic.
LINK TO A TOPICAt the top of the page you're viewing, find the breadcrumb navigation. It looks like this:
The 10-Page Torture Test » Clark Nova » The 10PTT Forums » 10PTT: When Yesterday Was Tomorrow by Daryl Zer0The format is SITE > FORUM > SUB-FORUM > TOPIC.
Click on the TOPIC name to refresh the page and return you to the beginning of the topic. The address in your browser will look something like this:
http://10ptt.com/smf/index.php/topic,296.0.htmlScroll to top of the page to find the SHARE button, click it, and link you post to your other networks will go to the first post in that topic on 10PTT.
LINK TO AN INDIVIDUAL POSTThis is quicker. First, find the post within a topic that you want to send to your social networks.
Look at the post header. The heading is a clickable link prefixed with this icon:
Re: 10PTT: When Yesterday Was Tomorrow by Daryl Zer0For the post you want to link, click on the header link. This will refresh the page and position your browser at the selected post. If you examine your browser address box you'll see a URL similar to:
http://10ptt.com/smf/index.php/topic,296.msg1295.html#msg1295That designates a link pointing directly to a post within a topic.
Scroll to top of the page to find the SHARE button, click it, and the link you post to your other networks will go to your chosen post within that topic on 10PTT.
