What does it mean to 'Gather Users'? Well, it means that when you look at any page on YouTube's website, Tube Toolbox can extract every username that is visible on that page. Once you have gathered users, you can perform automated tasks such as sending them messages and friend requests.
The Spider Search in Tube Toolbox allows you to gather users based on age, location and interests.
This feature in Tube Toolbox allows you to pick and choose certain users from the current page. Generally you won't need to get specific but there are times when you might only want a select few users from the page rather than all of them.
This feature allows you to gather all users and/videos from the current visible page in your browser. One cool feature is that if you are viewing a list of pages (search results for example), you can have Tube Toolbox automatically cycle through all of the pages. You can also add additional filtering based on how many Friends/Videos/Subscribers a user has.
This works exactly like 'gather all from current pages' except you enter the search term into Tube Toolbox rather than into YouTube.
This is another way to quickly gather a particular person's Friends, Subscribers or Videos.
