Thanks to all donators, mostly from Patreon and Liberapay, we managed to upgrade the server so we have more space to store the content produced in the wiki.
We have stored every fund we have in a Brazilian bank, away from the dollar, and because it's easier to manage given the current staff of administrators. Upgrading the server cost us in total R$1243.40 (~US$247.39). This includes taxes in international transactions (R$13.91 Brazilian international exchange fee + R$57.09 exploited by PayPal) and a US$49.50 service we requested so the disk could be extended. The VPS server itself cost us US$183.5 for a whole year.
After paying for the host, we now have available R$3342.46 (~US$664.48) in funds. There is currently no plan for this money, and we are just storing it so we can pay for hosting for more years. We reserved a part of this money (R$2500.00) in savings which have earned us an extra R$33.17 passively, which is a minimal, but safe investment, and still better than just letting the money alone.
Any suggestion on what to do with this money is welcome. Thank you all for making ProleWiki sustain itself for one more year!
