You can access all of your posts ... click on Your screen name ..anywhere on site ..but upper right after Welcome. will do. Then click on "Statistics" and then "find all posts by sunflower55" ...
You can also access anyone else's posts the same way.
There is also an "advanced search" option... click on that on the upper right, above the task bar with COMMUNITY on it. Then you can select a person's screen name, or a key word or a date to search... read down through the page of options...
You can subscribe to any thread you want to follow... click on THREAD TOOLS above the thread (on the right as well) and "subscribe" that will put the list on your profile page. It helps best when you open to your profile page rather than the forum index, if you mainly want to follow threads.
