I recently tried embedding TALKI into my Joomla site. TALKI is a forum you can embed with a short and simple line of code. You can embed your own empty forum or use an example forum that is already filled with a number of posts. I chose the latter option; it makes it look like people actually visit your site! TALKI is a web 2.0 application in as much as: it allows you to sign in with Twitter, Facebook, Google, Yahoo, Open ID etc. Your avatar is automatically imported, but that seems about it. Apart from that, apart from the Wordpress plugin that is offered, it's pretty much a straightforward forum. If you want to go for the paid options more features are available, but If you have a website with PHP you are much better off installing a forum like SMF or PHPbb. With a self installed application, you obviously have complete control over content, user management, attachments, add on extensions etc.; the whole shebang and completely free.
TALKI is a new startup and the developers are upgrading the system and fixing bugs. Many users on the TALKI forum have suggested improvements to the system. There is a section on the site that allows you to vote for particular improvements: http://talki.uservoice.com/forums/42301-general It is here that I noticed a number of users asking if there was a way to embed TALKI into Joomla. I worked out a simple way of doing this when I messed around with the program; I posted the solution to the customer feedback forum. To my great surprise, I found that my post had been deleted the next day. I checked my original post on the embedded TALKI forum and some of my posts there had also been deleted! (I think I mentioned one of their links wasn't working). No, I did not engage in any foul language, flaming or bad netiquette of any kind. This is of course the main drawback with a forum like this. Not only do you have no control over the style and formatting, you have no control of the content.
Since TALKI's admin has removed my instructions on how to embed it into Joomla; I will share them again here:
