Hi there,
I'm glad to tell you that the TDF board has approved a budget for
travel bursaries for the HackFest - details on above wiki page,
executive summary:
* transportation-only, please sign-up for coach surfing if you need
free accomodation
* volunteer-first - people affiliated with a company involved in
LibreOffice work will come last
* first-come-first-served - participants will get reimbursed in
order of their sign-up on the wiki attendance list, until budget
runs out.
Please be economic and pick cheap travel - that said, flights to
Hamburg might still be available at a reasonable price.
Looking forward to see many of you there,
-- Thorsten
