Unfortunately, I can't find the threads in which I have been helpful to new members. The only way I could is if I were allowed to use "Welcome" in the search program but it is rejected because it is too common.
Hence, no extra point for me.
Five posts?
Here is my first post ever. It was in the Delta Forum and demonstrated how the airline was hurting itself outside of America.
The second post, while not particularly fantastic in itself, started a phenomenon: The Unabashed Cholula Spam Thread. This ran 5544 posts before it was eventually closed -- and even then was replaced with the Delta Forum Lounge Thread. Other forums have copied this idea, which allows for members to post all their off-topic fun in one thread, thus not cluttering up the board.
The third post started in Omni, was moved to Travel Safety & Security, and eventually to Community Buzz. It touched off the thread with the second most number of views in the history of FlyerTalk (currently at 371,161); received world-wide attention off of FlyerTalk; and brought many new members to the board -- quite a few of which have proven themselves to be very valuable additions. (In addition, it helped save what little sanity I have during a very difficult period.)
The fourth post is one I am especially happy to plug here. It is for the upcoming PBI-FLL Meet in December and you still have time to sign up and join us.
Finally, the fifth post is one where I stuck my head into the lion's mouth. The Travel Safety and Security Forum is FlyerTalk's hotbed of TSA-bashing. Even experienced members who should know better feel free to use the most exaggerated terms to denounce this very unpopular organization. Worse, some tar all TSA employees with the same brush -- which is specifically banned in the TOS. Although no fan of many TSA policies, which I feel serve little purpose, I felt that these kind of posts, which belittle all TSA staffers (including those who are F/T members) are not only distasteful but their extremism actually undercut the valid arguments against foolish policies like the new "Ziploc" rule.
