I've created this simple nice looking font in Paint (it consists of few pixels per symbol) and I wonder how I put this in a file appropiate for submitting.
The spacing is irregular because of the used style. It already has certain colours, so I don't know if it's even allowed to be submitted :/
Should I post a picture of it all here, so you know what I'm talking about?

If you would like to create your own font, here are a few tips: http://www.dafont.com/faq.php#create

No need. You have made a series of images. As these (can) have more than one color they can not be converted into a font.

Well, I'll share it anyway just for the attention :^)

Wat vind je qua ruimte tussen de letters het beste eruitzien?

Wat ik vindt dat er het beste uit ziet is niet zo relevant. Some like it hot, others not.
Van wat je laat zien kan geen font gemaakt worden. Twee kleuren en als klap op de vuurpijl één van de twee met een toonverloop. Dit is zelfs als photofont niet bruikbaar, niet schaalbaar. Als je hiermee door wilt gaan rest je alleen de mogelijkheid van een vector plaatje van elke afzonderlijke letter/cijfer. Plaatjes rijgen is alles wat hiermee gedaan kan worden.

A font can't include color or grey. A font is alway just black and white (or rather full and empty).

Menhir, the OP has no idea what it is talking about. It thinks fonts are bitmap images. Now see why the use of the word font leads to this sort of misunderstandings? Again, a font is a size (in points) of a face of a type. Not an image.

To be a usable font, it has to be in a font file format. There is a such thing as bitmap fonts but I don't know much about them; I don't know if they can include colors or if they must be in black and white. Bitmap fonts aren't terribly common though because they are not scalable (in other words, they cannot be resized) and the file size can be large. Most fonts people use are in some kind of vector format, which is a set of geometry instructions for drawing each glyph (a glyph is a letter, numeral, etc.). These are always black-and-white, or rather, they contain "fill" and "no-fill" areas. Your word processor, browser, etc. will make the fill areas equal to the text color and the no-fill areas equal to the background color. So shading, multiple hues, etc. are not possible in an ordinary font file. Sorry! Maybe someone more knowledgeable about bitmap fonts can help you out more.

ginkgo, this has been explained extensively to the OP in the OP's mother tongue. Thanks anyway for your contribution.
