It's a challenge.
I use the list of my postings (have you been paid yet link to bonus) to find a post that I've made and want to see if anyone's responded.
Have discovered that you need to go to the proper forum section (or maybe the "discussion" category to get the search to look at all links below that. Ie you can't be in "Support" to find something in "Contests"
Think ahead -- if you type something and no you want to come back to it, type in a catch phrase that is easy for you to remember. I've used "yikes", but anything unusual will work. Then finding the entry with "search" is a little easier -- if you're in the right section.
