Tips and tricks
Gaining more XP in dense jungle
When surrounded by a number of blocks that have a "Chop" button instead of "Move" button, you can click each Chop button in turn and possibly gain some XP from the chop action (as per XP Gains) but without actually moving. Once all Chop buttons are clicked, pick another place to move to and repeat.
Profile descriptions with blank lines
To add a completely blank line in your description, simply press enter once, type a single space, and press enter again. The space in the middle prevents the double enter from being shrunk to a single <br> tag.
Images for profiles
I'm not all that good with graphics, so I used the South Park Studio to make a simple picture to go on my profile. It lacks a 'Save' function so you have to take a screenshot and crop the image to suit.
When you enter the url of an image, make sure the picture isn't too wide as it looks rather squashed on the page unless you're using a rather high resolution monitor.
