You did not miss the introduction page for the Forumosafieds, because there isn't one. I am sorry for the confusion.
You can find the Forumosafieds here: viewforum.php?f=139
- and you are free to post there like any regular post on the rest of the forums.
The plan has always been to build a brand new classifieds website for Forumosa. This is still the plan. I hope to make this happen later this year.
In the meantime, post in this feedback forum if you have any other questions about the Forumosafieds
