Here's how I TexAgs... Make a Bookmark for each forum you visit, or for all of them. Place a shortcut for each Bookmark on a home screen, and then drag one on top of another to form a group/folder. Name the group/folder "TexAgs" and then drag all of the other bookmarks to it one at a time.
Once that is made, when you tap the group/folder, you can then easily choose from all of the forums you have added. Easy, organized, quick to access, and works well for me.
