How do I find a discussion that was already started?

And thanks everyone who replied!

Thank you, freqflyer!

PCVS, if you had written a post on that discussion it would be easy to find... go to the top right corner of this page where you will see SEARCH SITE.... now type in your screen name.... up will pop discussions/questions that you had posted upon. Hope this helps :)

If you know the author of a discussion,
If you know the name of a contributor,
Put their name in the search bar, see what comes up.

If you are looking for something you have seen and want to return is different than if you want to see what's out there as topics of a discussion.
Go to the blue bar above, click on forum, look around.

Also, anyone can start a new question or discussion.

You can also, if you require extra help, type in your topic or question here and someone may research it for you, then get back to you.

Is it a specific discussion? If so, you could search on the keywords, but sometimes you have to search a few times before getting the hits for the right thread you want.

If it's a general idea, as CWillie suggests you can also search on key words.

If it was the former, do you recall words from the title?

If you commented previously you should find it on your "news feed" page. If not on the main forum page you will find the most recent questions and discussions, at the bottom of each you can opt for "more discussions" and it will expend that into infinity lol.
You can also try typing pertinent words in the "search site" box.
BTW, if you want to follow a thread without commenting you can hit "follow comments" below the original question/discussion.
This all applies to working on a computer, if you are working from a phone or tablet I understand things may be different.
