The rules are simple:

The post can be a single image, an image gallery, or a link to a specific comic hosted on another site (the author's website, for instance).
The comic must be a complete story.
If it is an external link, it must be to a specific story, not to the root of the site.
You may post comics from others or your own.
If you are posting a comic of your own, a maximum of one per week is allowed (I know, your comics are great, but this rule helps avoid spam).
The comic can be in any language, but if it's not in English, OP must include an English translation in the post's 'body' field (note: you don't need to select a specific language when posting a comic).
Politeness.
Adult content is not allowed. This community aims to be fun for people of all ages.

This is a misapprehension. Springs are on hillsides, not hilltops. Basically, imagine there are two surfaces: the ground, and the water table. In some places, usually on hillsides, the water table will intersect the surface. Where that happens, a spring will exist.

But that water has to be under pressure for this to happen -- this is known as the hydrological gradient. Water flows down hill on the surface, and down gradient under ground. In order for there to be pressure on the water, enough to force it out a hillside, the water table somewhere in the hill needs to be physically higher in altitude than the spring.

In other words, it rains on top of the hill, and the rain soaks into the ground. That water wants to flow downhill, so it flows out of the ground on the sides of the hills. But this means a spring will never flow from the top of a hill.
