I posted about the camp on a handful of relevant Couchsurfing groups.
One guy from Nigeria has messaged me:
Hello Daniel,
I saw your post title "Free skillshare and maker camp at Open E Land
Extremadura" which will be taking place in Spain. I will love to attend
this work shop but i need your assistance in securing a visa to your
country.
I will really appreciate it if there is any assistance you will be able
to do for me in term of paper work so that it will be more easier for me
to get a 3 months visa or less
Regards

Hi Alex, be great if you can come over but I'm not sure we're in a
position to help. We're not a legal entity, don't employ or officially
educate, I don't think there's really anything we can do in terms of
sponsorship etc.
To be honest I don't think it's something we thought to look into, but
might be a good idea for the future...
I'd recommend having a look around this forum:
http://www.immigrationboards.com/
as it has a lot of information and really helpful people. If you do find
a way in which we can make things easier for you, let us know.
Sorry I couldn't be more helpful,
Daniel.

Thanks for your quick response to my email
i really understand what your organization is up to. what i need is just
an invitation letter probably with the organization letter header paper.
is just like you sending me an invitation letter to come over.
These is how is staed on the website
" If visiting friends or family, you must provide letter of invitation
with the contact information of the host and visitor, purpose and
duration of the visit, confirmation of accommodation including the
address, signature and date. You will also need to provide proof of the
host's status in Spain ie. copy of their Spain passport's information
page, or, if they are not a citizen of Spain, copies of their Spain
residence permit and their national passport's information pages."
you can as well check this out

invitation letter will look like,ok
