Help with posting a add
 

How do I become allowed to post a add in the classified adds????

you "become allowed" by posting a minimum of 10 good posts, and the classifieds open up to you.

this isn't auto trader, and we dont want every slap-ass with a blazer to dump, filling up the classifieds. knock out 6 more posts, and the world is your oyster

Have a read through the announcement in all of the classifieds sections for all of the requirements:
