Voting will start tomorrow for shop=tortilla at the proposal page. I am not familiar with mailing lists, so, please, cross post this announcement on the tagging mailing list on my behalf by sending an email to: tagging@openstreetmap.org. If you do, I will appreciate it if you comment in this thread that you did crosspost my call for votes on the proposal.
I went ahead with the voting process since there were no more new comments in the RFC for a couple of days now.
Please vote YES! Am I allowed to vote, by the way? Proposal:Shop=tortilla - OpenStreetMap Wiki
UPDATE/VOTING RESULTS: The voting period finished just yesterday and the proposal got approved with 32 votes for, 1 against and 0 abstentions. I will keep working on this further, but I wanted to announce the results here too.
