Shows you at the bottom of this post... http://forums.toucharcade.com/announcement.php?f=2 Or simply press 'quote' and you can see the code they use for the post
Simply get your Apple Store link and put it between special tags, like so: [appinfo=all]LINK[/appinfo]. You may also be interested in embedding videos. For those, you need to take the unique ID of your youtube video (the part that comes after the " = ") and put it between special youtube tags: [hdyoutube][/hdyoutube]. Let's use the YouTube link [url]https://www.youtube.com/watch?v=J2HBdRCroks[/url] The unique code is at the end, J2HBdRCroks. Your embed code should look like this: [hdyoutube]J2HBdRCroks[/hdyoutube].
I assume you are talking about this thread - http://forums.toucharcade.com/showthread.php?t=264621 (Abyss of Magic [Free , Puzzle RPG]). If that's the case, the link you had at the bottom was not an embed link, but a simple URL - which is not picked up by the TA systems. I edited your post and changed the link to look like this: [appinfo=all]https://itunes.apple.com/nz/app/id961376638[/appinfo]. It should work now. (Although your image links are broken at the host, and that's not something we can fix)
