First off, welcome superhero. Don't worry about being slow, Rome wasn't built in a day, and neither was wikipedia. If you look on the project page in the section on grouping userboxes, you will a few options on how to add userboxes to your userspace.
I'll even show you the option I use.
The option I use has userboxes going across the page, you can have a maximum of four boxes going across the screen when the screen is maximized.
If you need more help, fell free to ask, nobody bites around here. Salisbury Steak (complaint dept. - contribs) 01:31, 19 July 2007 (UTC)[reply]
These aren't my userboxes, just examples on how I use them on my userspace.
I go three across, so I have space on the right side for other stuff to go down the right side like a table of contents.
