I fully support the 300 posts for a non-supporting member to have the opportunity to mess over someone.... 30 posts can be made up non-sensically but if someone posts up 300 BS posts, EVERYONE on the forum will know not to deal with them.
If the person is willing to support the forum, they can post in the classifieds much sooner than 300 posts. Revin-it02, you're a supporting member with 30 posts... you can use the classifieds...
