Since Alovoa is a FOSS project, it probably won't have a lot of resources to market itself to gain more users.

I suggest you make flyers in digital A4 format, so anyone can print them and post/stick them on their local bulletin boards or anywhere that's allowed, so community itself could be physically promoting/advertising it.

Regarding the format of the flyer, .pdf would probably be most popular to use, and also one in an open standard format that LibreOffice uses.
