Attention: In the SprayCan App it is possible to use a lot of different signs, glyphs and emoticons for your username. However, there are two downsides:
1. Many of these signs can't be displayed properly on the SprayCan website.
2. It is very hard for other users to find you via the search option, because they have to identify and type all those fancy little signs.
We recommend strongly to use only letters and numbers for your username which can be found on your keyboard!
