Just like previous years, the @t-r-f Travel Reimbursement Fund is an 'donate any amount'-cause and can be used for anyone attending SteemFest to relief (some of the) travel expenses of SteemFest attendees and will be distributed after the SteemFest event to attendees who applied in person at the SteemFest Desk during Conf Day 1 & Conf Day 2:

TLDR: By donating (really any) amount of Steem / SBD you enable SteemFest attendees to make it to Kraków!

@t-r-f Travel Reimbursement Fund successfully worked in both 2016 and 2017 and has distributed:

Year	Steem funds	SBD funds	Number of applicants
SteemFest 2016 - Amsterdam	1034	7853	53
SteemFest 2017 - Lisbon	5000	4000	133

How @T-R-F works for SteemFest attendees:

In Kraków on Conference Day 1 & 2 you can apply for the 'Travel Reimbursement Fund' during coffee breaks by registering the trip details at the SteemFest Desk and by showing proof (a boarding card for example) and your ticket (can be on your phone).
Reimbursement will be based on miles travelled (as generally the further, the more expensive). Starting point will be the distance from the airport of departure to Qubus hotel in Kraków. The distance is based on line-of-sight straight point distance, not via via / stop-over distance. So, the 'SBD/Steem per Mile'-rate will be the same for all.
At the end of Conference Day 2 (18:00 / 6 PM) the application entry closes and by doing a simple calculation the total amount of Miles travelled by all applicants is available.
Also the total funds available right here on @t-r-f is available so the SBD/Mile & Steem/Mile rates can be established and the payouts will be automatically executed via a script soon after SteemFest. Applicants will both get Steem and SBD.

Note: You can only apply in Kraków for the @t-r-f at the SteemFest Desk during Conference Day 1 & Conference Day 2. You don't have to apply to @t-r-f.

Applying is not obligatory: Anyone who is not applying is basically leaving her/his piece of the pie over for the others to enjoy, which is generous.

@t-r-f is open for funding!

If you want to support fellow Steem users attending SteemFest to lower their travel expenses, please supply any amount of SBD or Steem you want to donate. Simply transfer any amount of SBD or Steem to @t-r-f (note the dashes between the letters!) or use the fundition cause!
